April 3rd Webcast - Advanced Road Design in InfraWorks

hello everyone Eric Chappelle civil community evangelist for Autodesk and I want to thank you all for coming today for today's webcast it's advanced road design with infraworks and I'm kind of flying solo today normally I'm introducing another presenter and then they take the take the wheel for the remainder of the hour but today I'm going to be your presenter as well now I'm not totally flying solo because I do have Elliot Rosenfeld in the back in the background who's going to be fielding questions as they come in and I'll talk a little bit more about questions in a bit if you're new to our webcast series I want to welcome you this is something we we do twice per month or try to and we try to do it on the first and third Wednesday's of the month and I have usually in parentheses there because as is the case with this week we sometimes are not able to meet that schedule exactly but it turned out okay we still got tons of registrations for today's session so it turns out that Tuesday works well for folks as well so again appreciate you all giving an hour of your day to to join us the goal of the series is to give give you information about our civil products and their features oftentimes we do this from from the perspective of the product team because we know that those are the folks you guys want to hear from the most the folks that actually make make the software it's also a chance to for you to ask questions and provide feedback on whatever topic we're discussing I'll even give you an opportunity in just a moment to suggest topics for upcoming webcasts so you know we really want to give you an opportunity to let us hear what what's on your mind also or in general the goal of this webcast series as it has been for almost three straight years now has been to just bring you folks the users of our software a little closer to us the makers of the software and hopefully we've been doing that over the years our next webcast will be in two weeks it's Wednesday April 18th same time same place twelve to one we're going to be covering what's new in civil 3d and infraworks you're going to hear from Dave Simeone and Sarah Cunningham product managers for civil 3d and infraworks respectively and you'll be seeing information come out on that in your email and also on the various various sites listed in the bullets on your screen the community site the forums Facebook Twitter Linkedin and so watch for that announcement to come out in the next few days as I said earlier we would love to hear from you as far as what you'd like to see in upcoming webcasts so you can just use the questions panel as part of your GoToWebinar interface and just type in their you know idea for upcoming webcast and tell us what it is and will we download all the all the logs from each webcast and we'll keep that on file and when it comes time to plan out future webcasts we'll look to that as a reference and look at your ideas so please share those with us most times you guys are able to come up with much better ideas for webcast than we are so we appreciate your input on that I want to also draw your attention to our Autodesk civil engineering Community Center the URL is civil - community autodesk.com this is an awesome central hub for everything autodesk civil infrastructure news channels through here forums the user forums are gallery where you can publish projects that you're working on and kind of share them with the world and get feedback and kudos and answer questions about stuff you're working on lots of tips and tricks updated every day the tips and tricks content is updated every day so is the learning content saying with news content as well we feature a gallery project of the week we feature ideas and forum posts from civil 3d and infor works so there's something new up here every day and in some cases like the trending stream it's updated you know hourly so there's always something new every time you you come up here definitely a site you want to bookmark and visit regularly daily if not more often it also has a cool search feature so if you heard something you heard there's an update for for one of our products or a new release or a patch or something you can go into the search feature at the top of the page and just search and it will search the recent looking at kind of the most current information about about what what you're interested in so that's cool too little disclaimer I don't think we're gonna get into this today we may but if if I talk about anything that's forward-looking like things were working on in labs or in beta versions of the software or anything in general that we're working on as far as functionality please know that there's no guarantee that anything we talk about that isn't actually in a supported released version of the software there's no guarantee that's going to be there until you actually see it in a released version of the software so please don't make any purchasing decisions on anything that we discussed that is this is something we're working on let's say that's what this big disclaimer is all about encourage you to ask questions Elliott is a very capable question answerer you knows the software very well and he's like I said going to be watching watching the questions panel so the more questions we have the better the presentation gets so please don't hold back and ask your questions unfortunately we can't open the phone lines we've got way too many people for that but you are welcome and encouraged to use the questions panel in the in the GoToWebinar interface so with that I'm going to jump into my presentation which is advanced road design with infraworks and strangely I'm going to start off in Google Maps because I want to talk about an interchange area that I am familiar with I've got a bittersweet relationship with this is breezewood Pennsylvania and you know I grew up in southwestern Pennsylvania and but I've lived in Virginia for I don't know over 15 years now so I travel home a lot to see my parents and every time I travel home I have to use this interchange so I thought this would be a great way to to build something in infraworks that I would personally love to see and a good a good you know real-world project that we can look at so let me tell you the problem at least from where I see it personally when I'm traveling home I'm coming up Interstate 70 it's actually East it looks north here so let's just call it North I'm traveling up interstate 70 north and when I go to my my wife's parents my in-laws we have to get on the Turnpike here and head west on interstate 76 and what I have to go through to do this is drive north until I hit a t-intersection with us route 30 there are traffic lights here so I have to come up to this T intersection deal with this traffic light usually there's traffic backed up all through here because there's a lot of trucking traffic there's a major truck stop back in here over here is a truck stop there are hotels just a big a big cluster of commercial and just traffic everywhere this picture doesn't do it justice because they must have taken this like on a Sunday morning or something but anyway I have to come through here through a couple of traffic lights and then get on this connector road and travel the whole way over here through the toll booth and eventually on to interstate 76 where I head west I've always thought that's a horrible setup it's if it's like I said it's a traffic nightmare having to go onto this you know very commercialized road here to get from one interstate to another why isn't there a direct connection between Interstate 70 and interstate 76 so that's what I'd like to work on today is making this connection from directly from 70 to 76 and I'm going to do it in this area right here now we don't have time infraworks is fast but we can't build an entire we can't do build to complete interchanges in an hour so I'm just going to focus on this this side over here so let me go into infraworks now and I've built a model out of this you know using model builder and you can see it here I'm in the master I'm in the master proposal and let me just show you what I kind of ended up with the first time I ran through this I'm switching to a different proposal and you can see I've got one interchange here on the east one on the west and then in the middle is just a rough depiction of where the toll booth might be we're gonna focus on this interchange right here now I realize not all of you on the call are doing you know highway projects but I'm going to show you a lot of little tips and tricks and techniques and how things go together that I think are going to help you in all types of projects you know Residential's residential projects have roads even commercial site projects have you know access roads and things like that where these these tools are going to come in handy so let's switch back to the master proposal oh and one other thing I want to say about this this is my first crack at this design and I've done it a few more times since then but one thing I realized that I did that wasn't very bright is I passed under the turnpike which is you know one two three four five six lanes divided highway I mean these bridges that I would have to build are going to be really expensive what I really want to do and I'll just jump to another proposal here is I want to cross over top of the Turnpike so that I'm building a bridge that's for a two-lane road rather than you know a five lane or six lane divided highway obviously going to be a lot less expensive the other thing I did is rather than travel through this valley over here where I could go under the turnpike I decided to come up here on the ridge line where I could travel I'd already be elevated and it would be easier to travel over the road I'm just sharing like my thinking as I'm going through this remembering also what infraworks is intended for right we're in the early part of the project we're doing proof of concept we're trying to maybe do a couple of different alternatives of how we might design in this case an interchange so this isn't going to be you know designed to the finest detail but we do want to get something that would work and that looks good and that so that's going to be our goal all right so I'll switch back to master view or master proposal and I'm going to make a a new proposal out of that one to get started so I'm literally starting from scratch here I'm going to call this I think I'm up to design five so let me go ahead and type in design five and now we've got identical proposal to master but it's called design five a good a good rule to follow is to keep your master proposal intact and when you want to do design just make a duplicate of it and do your design in there all right the first thing I'm going to do is get rid of my planning roads that represent the turnpike here and yes I know I can right-click and convert this to a component road but I really don't want to because it's got all of these vertices and I have this really nice sweeping curve here that I'd like to define you know with with geometry that is representative of the long sweeping curve and also because I've got the new element based layout it makes this really easy so I'm just going to wipe these guys out these planning roads the other thing I want to do is this is currently being being depicted as to individual roads and I want to depict it as one divided highway so all I'll do next is go to my roadway tools I'll click my component Road tool for my assembly I'm just going to use something simple here I tend to gravitate toward this two-lane as a starting point when I when I kind of don't know what what my next step is and watch how nicely this element based Road design works notice I'm switched here to element based when you when you install a new version of infraworks and you go to draw your first road it's going to default to P I based so you have to come up here and click it to element based then all I have to do I'm going to define this tangent first click a point along the tangent it automatically assumes that I want to do a curve and jumps right into this curved section of the road it's not a perfectly defined depiction of the curve that's because of my inaccurate clicking and I can fix that I'm just going to double click right here but I've got a tangent with a curve the next thing I'll do is I'll click on this gizmo here for this tangent I'm going to hold down my shift key and drag it northward and the reason I'm holding the shift key is because it keeps it aligned with the tangent won't let me swing it left or right it keeps that original alignment and I'll just swing it into position so it's splitting that median that looks pretty good right there all right so now I've got a nice nice geometric representation of that existing road so you know rather than convert it I just erased it and redrew it you know my ultimate goal is to have a component road here that I can tie into and take advantage of all the you know the intersection capabilities and all that so that I'm intersecting you know component roads with component roads now my next challenge is I've got a simple two-lane road here and what I need is a divided highway that has three lanes it's actually eastbound but I'm going to call it northbound has three lanes eastbound two lanes westbound what I would do is you know sit down and add my components right so I'd right-click insert Road component at a median at a lane add more lanes on the left and you know get it all built out just save a little bit of time what I did is I did that earlier in one of my several times that I've done this I saved my road as an assembly I'm going to show you how to do that later on with a simpler Road so this will save you from having to having to sit there and watch me build this out component by component but what I'll do here is say Road assembly replace assembly and I've got one in here called route 76 I tried it got it a few times here number three was the charm so I'll just click that drop my assembly on here and then you know you can click and drag this assembly insertion to define where you want it to start and end in my case I want it to be the full length of the road so I'll click the gizmo here and I'll say a line to start of Road and a line to end of Road now based on my experience with you know teaching this stuff to other people to some people that's a trick they didn't know you had that a line to start of Road and a line to end of Road I'm going to press ENTER there by the way to finish the command so you know the way I'm gonna run the webcast today is I'm just gonna build this thing and and tell you what's in my mind while I'm building it realizing that some of the things you already know and some of the things maybe tips or tricks to you that you didn't know and hopefully we'll pass along a lot of information so you can see now I've got my nice five lane divided highway it's got paint stripes it's got shoulders it's got the grass median and I'll tell you a little bit about how to build that individual stuff a little later but I've got a nicely defined depiction of my of my Turnpike here that I can tie into so next what I'll do is I want to define my Road along this ridge line now it's pretty easy to see where the ridge line is but just to make it a bit easier I'm going to take away my aerial imagery now that I've used it to define where the road is I can I can remove it now if you had the road surveyed you could certainly you know if you had that centerline in civil 3d you could certainly bring that in and have an exact location of where the turnpike centerline is you know you've got you know especially if you've got the AEC collection you've got civil 3d at your fingertips you can accurately accurately define geometry in there and bring it in here but or you could also do what I did which is maybe more typical of you know early on in the project where you haven't done a survey yet you're just maybe doing some proof of concept or some studying for the for the d-o-t to see what what might work here so anyway as I was about to do I'm going to turn off the aerial imagery so what I did is I promised you I would share my thoughts as I worked I went into my orange basic info Works toolbar here I clicked the cube icon and then went into surface layers and from here I can turn off my imagery and click OK I'm also working in engineering view which takes out the sky and the shadows and things like that one thing I did though is the default kind of setting for engineering view is to have the high visual quality set to low and I thought since you know since this was a presentation I'd want things to look a little sharper as I worked so I switched that hi visual quality and I'll show you the difference here if I switch it back you know the lines get a little a little thready things aren't quite as sharp so I thought just for you guys today to make it look good I would switch to high visual quality but for just working on my own where I'm the only one that's seeing what I'm doing as I work I would probably keep it at low visual quality so I get the highest you know the highest performance in speed out of the out of the model all right so now I can very clearly see where that ridge line is so I'm just going to come here and launch my component Road command once again I'm just using that to lay in style I'm going to come from over here somewhere if you do a little curve up this way a little curve by a short tangent curve back the other way got to love this component or this element based layout I'll come across this way start my big sweeping curve here a tangent another curve and then I'm being deliberate about tying into the Turnpike with a tangent here let me just double click that and I'll kind of explain what I mean a couple of things about what I just did first of all notice that I tied into the center of the Turnpike even though in your mind you might think I need to tie into this right lane because that's what I'm merging into roads intersect centerline to centerline and infraworks so that's where you need to double click on if you want to tell infraworks that you want an intersection another reason I used a tangent is because and this is a good thing to demonstrate something you may or may not know I'm going to do just a really quick component road here a really quick intersection just off to the side so we can talk about it and another thing I'm going to do is I'm going to take away the the left lane okay the the backward flowing lane now look at what happens right now I'm intersected at a pretty pretty sharp angle let's let's switch that to roughly 90 degrees okay and look at what you get you get yield lines and traffic arrows this looks like your standard you know 90 degree intersection a one lane road maybe in a town intersecting with a you know with a two lane road with traffic going in both directions but if I swing this around and make it a sharper angle infraworks is smart enough to say wait a minute I looks a lot like a ramp and it automatically takes away all of the yield lines it adds an acceleration or deceleration Lane depending on the configuration and automatically adds that widening and of course if you know anything about widening z' you know that you can grip grip those gizmos and stretch out the the length of the acceleration part the length of the transition and so on so we're taking advantage of the fact that when you intersect two roads together and one of them is only going in one direction you automatically get this ramp configuration you know let the tip here is let in four works do that for you now you might be wondering on what the heck's going on here that is one nasty looking thing well what I what I haven't done is I haven't taken taken away this Lane that's this heading in the other direction so this looks like you know some really ugly conglomeration here until and this is the trick this is where people can get tripped up they draw this in with infraworks they see this and say oh man that is not at all what I expected and maybe something a little harsher than that but you got to understand what you're asking infraworks to do and all I have to do is pull this Lane back so that gets out of play in the intersection and then magically I have a very nice ramp interchange and I didn't have to do squat for that infraworks recognized that I was intersecting at a sharp angle with a lane going in one direction it automatically added the acceleration Lane in this case I can adjust the geometry you know I'm going to make that transition longer I'm going to make the acceleration area itself longer and now you know I've got a nice ramp interface there even even though I don't know that you'd have an arrow there but you know it's pretty pretty consistent with what you'd have and all I had to do was was simplify it to the point where it kind of makes sense you know you wouldn't intersect a ramp with traffic going in both directions it's only going to go in the flow of traffic of the main road something else that my throw off is you know I wanted to create an overpass here but instead I've got this really kind of crazy-looking intersection and you know just realize infraworks kind of did what you told it to do you you crossed over one one Road over another at the same grade it's going to try to create an intersection and it actually did a pretty darn good job it created the yield lines it realized that there are multiple lanes of traffic put all the traffic arrows in there that you need but it turns out that's not really what you want you want to do an overpass here so to make that happen I just simply need to elevate my ramp Road we'll call it our connector road up over the Turnpike Road so all I got to do is select the road and swing my view down so I'm looking at it to where I can see the PV is a PV I was created automatically at the intersection that's what infraworks does and I'm just going to click that and drag it backwards along the alignment of the road drag it to about right there and then I'm going to make another PV I on the other side of the road just right-click on the centerline and that adds my PV I for me and then if I look at my elevations and this is maybe one of the simplest but best tips I'm going to show you today all I'm going to do is place my cursor on the road on the Turnpike Road the existing Road under or near the bridge and I see down at the bottom left corner right down here my elevation is about 1421 all right and that if I look at these PV eyes this one's at elevation 1421 is really low this one's at elevation 1443 it's pretty high it's about you know 20 feet higher so 20 feets a pretty good place to start with I think with an interstate bridge to take care of the underpass clearance and the actual thickness of the superstructure and all that so I'm going to leave this one where it is and I'm going to bump this one up to 1441 and you can even get under there with your measurement tools and you know and measure the clearance but that'll get my one road elevated above the other and then all I have to do is add my bridge so one of my bullet point items in the description for the webcast today is creating an overpass and that's as easy as it is you you cross one road over the other you elevate it using your PV is and then you add a bridge okay now my pier here is a little bit in a dangerous place so I can either make the bridge a little wider or I'm just gonna click the pier and move it am I'm not sure why it moved just that part let's try that again here we go put it right them out there and now I don't have to worry about traffic running into my pier and you know I can check clearance here with my measurement tools all right something else I'm noticing and you know there is an I would I wouldn't say there's a step-by-step procedure to this you know do do this first in the second and this third this as I'm working on this I'm seeing things that maybe I don't like or need to fix I noticed that my slopes here go out a certain distance and then N and drop straight down and I know just from knowing the software that has that has to do with my grading settings for the road so I'm going to click the road go over here to grading and I noticed that my grading limit defaulted to thirty two point eight one feet well that's not enough for this three-to-one slope to daylight so I'm going to need to give it more distance maybe I'll try one hundred and fifty feet alright just type that in and press ENTER and now everything should tie into existing ground as I would expect it also while I'm here I'm going to change the grass I'm gonna change the cut and fill material to grass and I always like to use this under under terrain you've got these grass styles here that are scale dependent I always like to use those because they they look good no matter how closely you're zoomed in or zoomed out you can kind of see the difference here with with the median material you can see how it's has that tiled appearance actually I think this might be scale dependent too but with my slope material that actually changes and it looks good no matter how close or how far away you're zoomed in now while I was doomed in closely there I noticed that you know this this PDI is pretty harsh and if I take a look at it you'll notice there's no vertical curve there so I'm just gonna right-click that P VI and add a vertical curve it's gonna add a really short one I think no actually that's a pretty nice vertical curve now that does make the bridge more complex the fact that the vertical curve actually runs in two it takes a part of the bridge I might want to pull my PvP vi back away from the bridge so that I don't have that condition I can certainly do that if I want this PV is kind of sharp so I'm gonna lengthen that curve a bit so I'm just working my way through it as I go things are looking pretty good all right I want to see if I can tighten this up a bit because my my Curt my big sweeping curve is pretty far from the Turnpike so I'm just gonna click this this curve gizmo here and pull it in a little closer that's pretty easy to do and that's looking pretty good okay so now so far I've got access for people that come off of Interstate 70 which is here eventually I you know I would make an interchange over here and they would come along this road across the Turnpike come back around and enter in a nice or northbound we'll call it acceleration lane and get on to the Turnpike and head head in that direction okay now I want to make a place where people heading north or east on on the Turnpike and exit and come back around and over the bridge so to do that I'm going to create another component room and this time instead of a two-lane road I'm just going to go over here and pick a lane now I've racked up some assemblies in here so I am going to type in the word lane and that will narrow down my choices not much but enough to where this Lane this lane component comes in here now a single component and an assembly they're kind of the same thing so and that's going to become important in a bit but they're kind of interchangeable an assembly can be a single lane and that's all I'm doing right here is adding a single lane so I'm going to pick a point near the center of my main road my Turnpike and as you do this you'll kind of get better and better at knowing like where to pick things but I'm going to come out at an angle make a little curve and then tie in to the center double-click to my other road and hopefully I get a good intersection on on both sides and I do now I'll notice I've got this weird trying to come around and turn left I certainly don't want that so I'm just going to take this Lane and drag it into kind of into the intersection here and that should clean that up quite nicely for me okay now I will tell you it's great that that happened because I'm doing a doing a webcast and I would love everything to go smoothly but I can tell you that sometimes you don't get what I just got sometimes and I kind of hope it happens later on in the in the presentation but sometimes this intersection you know this one back in here it won't figure itself out and you'll just get one road over lapping the other and you just you kind of have to go and grab the gizmo and bump it around a little bit you may have to go into 3d view and take this P VI at the end and slide it up and down to get the intersections to find themselves and the same thing with you know with dragging this Lane back sometimes I go a little too far or not far enough and I get something that looks pretty funky in there you have to realise that you're asking in for works to do a lot it's calculating the horizontal and vertical solution for the intersections of the roads all at one time calculating slopes and everything and it's a pretty complex solution to come up with so sometimes you have to give it a little bump here or there to give it a chance to figure itself out so again just telling you what's on my mind as I'm working I see that sharp drop-off here again so I reminds me that I have to fix up the grading so I'll use that same grass material I'll extend my grading limit out to 150 feet and that's going to clean up my slopes a little better for me but I've got a pretty nice-looking set of ramps going in there something else I noticed is that we've got some pretty harsh change in elevation this one isn't too bad this one here is really bad you can see this very severe bump up here and what's going on there is you really usually oh this is a really good example of it here so what's going on here is the road is intersecting way way over here so it's grading you know straight from this PVI to whatever PVI is next it looks like this one here and because of that it's just so happens that the road lands way below the existing road up here so it has to make up that elevation difference rather quickly so a way to fix that and I'm just going to do it right here I'm going to add a PVI now what elevation do I set that PVI at I'm going to come up here and set my cursor to maybe a point across from it on the main road I'm seeing 1440 5.66 sounds good to me so I'll go ahead and add my PVI right here once my PVI shows up I'll click on it enter 1440 5.66 and that's going to bring that elevation of the road up to where it needs to be alright so I don't have that I don't have that massive jump in the road it looks pretty pretty darn smooth now alright and I could do the same thing here just grab an elevation off this side apply it over here and that would make that smoother for me all right so we've got half of our interchange done we're able to get off of the Turnpike and onto the connector road and we're able to get from the connector road on to the turnpike north northeast bound we'll call it Before we jump to the other ramps which will connect here and here I'm going to fix up some things on this on this ramp so right now it's just a single lane we don't have any stripes we don't have any shoulder so you know what do we do about that we certainly want it to look better better than that so I'm going to click on the road and I'll right-click and say insert Road component and the first component I'd like to do is a white paint stripe okay so as I look through the out-of-the-box components I don't see a white paint stripe on here so what I've learned to do is use a curb component so I'm going to grab this curb and I'll just drop it over here just a piece of it and you know as you might guess it it looks like a curb it's got a reveal to it it's made out of stone so on and so forth I want to strike so I'm going to click that curb and over here on its property is the first thing I'll do is change its width I'm gonna do 0.33 that's as narrow as you can go with a curb so if you're using 3-inch stripes unfortunately you can't go down to 0.25 you got to use point three three I'm going to use point five for the depth below and also for the depth I'm going to set those values equal and I'm going to say I don't want any deflection to the curb top and then the last little trick is I'm going to go to my material and pick the color white and now I've got something that looks a lot like a white paint stripe now it does have a half a foot depth if you wanted to get you know if you wanted to make it a really thin depth you certainly could but then you'd have a gap underneath you know if you're thinking about quantities and that sort of thing you know there is a narrow strip there but in any case I've got the I've got the stripe represented so the thing about that there's a lot of there were a lot of steps to that I had to bring the curb in I had to set its width I had to set its material to values on the depth I don't want to do that over and over and over again every time I want to add a stripe so how do I make a stripe component right if I again look over if I click the component roads tool I don't see you know there isn't a white stripe in here at least not out of the box so here's it here's a big trick for you what I'm going to do is I'm going to create a component road I'm going to create one out of a curb all right just a little piece of one right over here and I'll do all this stuff I just did right you have to watch it one more time I'm going to set the color to white I'm going to set the width to 0.33 depth below 2.5 and death to 0.5 and turn off apply deflection to curb top okay then so there's my stripe it's very weird I just got I've got this road which is a stripe but what I can do now I can click that quote-unquote Road right click and say Road assembly add to library remember I said earlier that anything can be an assembly even a single component so I'll go ahead and just click a point on there I'm gonna call this white stripe now I've done this a few times so I think I'm up to four I press ENTER and now I've got a stripe in my library I can delete that I can go over to my road over here my ramp right click insert Road component if I scroll down probably near the bottom there's my white stripe for and you can see I've done it actually two more times before that so now I can click that drop it in over here and I've got a white stripe alright now something else I might want on my ramp here are some shoulders so I'll select the ramp right click insert Road component type in the word shoulder here there we go drop this outside the paint stripe and I this I'd like to see three foot in width and I don't like the lighter color on the pavement it looks kind of weird so I'm going to change that to a darker asphalt color and you could do the same thing you know if that's the style of shoulder you like three feet with a with darker asphalt you can do the same trick I just did draw a road to the side that's nothing but that shoulder set up the parameters you like and add it to the library as an assembly I'll go ahead and do another shoulder over here and again I'll make it three feet darker asphalt and now because I know I've got other I'm gonna have other ramps in this project I'm going to select this road right click actually select it in a little too far there I'm going to right click and say Road assembly add to library I'm going to click the point where I'm right over the shoulder is full width of the shoulders and the paint stripes I'll call this ramp I don't know let's call this ramp X I don't know how many ramps I'm up to and here right now but now we've not we could not only capture individual components but kind of what the assembly capture was designed for the the idea is to capture the whole width of the road and all the components not just one although it works great for either one alright so now what I can do is I can apply that assembly to my ramp here so just to show you how it works I'm going to right click and say delete component I'll take this stuff away do the same thing with my paint stripe here delete component delete component and then I can right-click road assembly replace assembly find my ramp X there it is drop it in what I what I usually do is just drop it in and kind of see how it looks press Enter something to know sometimes you have to press ENTER and sometimes you have to just click off the road somewhere to get it to kind of take hold but now that I have this I can I can click these individual components and stretch them to where they need to be now this is where things can get a little interesting sometimes you need to stretch the component the whole way into the intersection which is what I did with the stripe and you'll get a nice merging of the two components okay so that worked that worked well the shoulder let's see how that works I'm going to do that with the shoulder again I'll click off the road and I can see that now the shoulders look good except they are different widths so you'll see a little bump right there now over here it may not work quite the same because of the different direction of the flow of traffic it may have to zoom in pretty close to pick that that striped component there there we go so let's see what happens if I pick the striped component and drag it the whole way into the intersection what's going to happen not good stuff right we've got the stripe that's just randomly going the whole way through so there are some cases where dragging it the whole way in is a good idea in some cases where I pick the grading there Oh No okay some cases where you kind of want to end it where the before the intersection happens all right so that's a little more like what we want then same thing here I can click and drag these components to back to whatever makes sense so I think on this side it's going to make sense to pull the stripe the whole way around I'm getting low on time here so I need to to move on but you get the idea actually what I'm going to do with this one I'm going to click it and say a line to start of Road and I'll do the same thing with the shoulder here Eric yes Elliot I started her up I just wanted to ask if you could try to zoom in pan a little bit less I think our bandwidth is causing a little bit of live music I will die we'll do that you know that's hard to kind of keep in mind but thank you very much ok thanks Elliot ok so by making that stripe and shoulder go the whole way to the beginning I'm on my way to defining that the two-lane portion of the overpass as well ok so let me put my last two ramps in those are pretty quick and simple and this time I'm going to actually use the assembly that I created it was called ramp X ramp X so making those assemblies is really a time-saver really handy and for this I'm just going to click near the center of the road I've got a pretty big elevation jump here so I'm going to make this nice and long so click near the center here a little curve and then a tangent here and I'm using that ramp assembly so it's um you know it's all going in the right direction now here's an example of where sometimes your your intersection just doesn't work out you can see that didn't merge it didn't it didn't figure itself out there so I'm just going to drag it try different spot I'm gonna look at the vertical you can see that it for some reason a douve way down on the vertical here it's got a lot of stuff it's trying to do so I'm going to pull this cube up to where it the elevation matches on the existing road maybe that'll get it figured out that's still not doing it I'm going to come back here a little bit there we go so now we've got an intersection that we can work with all right and look at how great that ramp looks because we've added we it was all the striping and the shoulders and everything we're built in automatically to the to the assembly that we used and then we've got one more here and when I've done this in the past I didn't have this weird serpentine thing going on here so this may get a little weird let's do this a little curve and a tangent notice again that I'm tying in to the center line double click to tie in to the center line and we got two great intersections there also remember that you know you've got lots of gizmos to work on the geometry if you want exact values you know again I think it's kind of overkill to get too picky about values here but if you wanted this to be exactly a 300 foot curve you could always click the tool tip and type it in you know you do have control over the geometry here all right so that's how you can leverage the capabilities of infraworks to build to build an interchange and just to show you another cool thing about the element based layout now that I've built this much if I wanted to continue designing the rest rest of the road you know I'm going to remove these horrible connector roads that are here now and I'm going to take advantage of the bridges that are already here and pass under them the nice thing now is I can start my component Road command and just jump right off the end of this road here and start start doing my thing right and it will just continue that that cross-section that assembly along the extended version of the road so that's pretty cool so there's some other things I wanted to show you that we're on the list quantities and sight distance and going to civil3d so very quickly I'm going to go through those things fortunately infraworks makes this stuff pretty easy so for example if I want to do cut and fill quantities I can actually just click the road and launch cut and fill and and hit the play button and it will give me my cut and fill values I can also hold down my control key and click other components so I've got my additional three ramps as well you can see everything highlighted in blue is what's being calculated for earthwork now I need to hit play again and you'll see that it'll calculate earthwork quantities for all the areas highlighted in blue now it doesn't work you need to know that it doesn't calculate quantities in intersection areas when it comes to like material quantities pavement curve and so on and that's kind of a bummer for an interchange design because a lot of what you do is is intersection area so you can see now the blue highlighting tells you kind of what's been the stuff that's not highlighted in blue is what's being left out on this quantity calculation so not as not as effective for an interchange design as far as material quantities go so that's how easy quantities are basically just click and and hit the buttons on the on the stack and you're good to go let's look at sight distance now I want to see if I have any sight distance issues on this road so I'll click the road click my little scale icon up here and then sight distance over on the right I've got my sight distance panel it's right now it's all I'm going to do the one lane because there's only one lane that's complete for the whole for the whole road so I'll go ahead and click analyze and what we're looking for are any red or orange areas that pop up and we can see one over here and I think because that's so far into the intersection we're not going to worry about it now in past times I've done this and maybe we'll see it on one of the other roads let's travel on the other roads let me click this guy and analyze see if any red areas pop up yeah that's what I was expecting so remember earlier when we had to fix the little PVI issue near the near the interchange near the ramp and here we see it very clearly we've got this let me close down analysis here we've got this very sharp jump up to from one road to the other and that again is because it's tying in really far away in the center of the road and the next high end point is way back here somewhere so we need to add a PDI to kind of smooth that out so again I'll hit the site distance you can see we've got this horrible sight distance problem here we've got more problems than just sight distance there well let's let's fix it and then see if the sight distance problem goes away so I'll close this down my elevation here is about 1425 75 I'm going to add a PVI I'm going to set its elevation to 1425 75 about the same as that the road I'm tying in to right across from it and then let's see if we have a sight distance issue now I'll click analyze no problem it goes right through now we're seeing another not sure what that one's all about we still have a little bit of a crest there so maybe I'll drop that down just a little bit let's go to 14 let's go to 1425 even go ahead analyze one more time still have a little bit of a sight distance issue there but at least that tells me it looks like it's where we're intersecting with Elaine so what we may have to do here is continue working on this profile maybe add a pvi here and elevate it upward a little bit so we can see over that little hump and then keep running the analysis until we get get that area cleared out all right so that takes care of quantities that takes care of sight distance analysis what about going to civil3d so what I can do here is the first thing I want to do is make sure my roads are named that's going to make life easier for me in civil 3d so I'm going to call this Turnpike connector look add an extra e on there for some reason and then I've got a few ramps that I want to register in here so looking at it this way I'm going to call this my North East ramp we had a question come in while you're showing the quantities that I actually didn't know the answer to no it's possible to view the quantities for all of the component roads in your model yeah you just have to select them all great okay so yeah um I don't know if that's possible it's possible select them all in model explorer but I mean typically you don't have hundreds of them so we're probably easier to just hold that control key down and do multi select or or you've got a number of selection tools you can select by window and stuff like that but yeah yeah and that was actually the follow-up question I think you may actually be able to right-click on a future class in model Explorer and do a select all yeah our view and data won't select from there yep great okay so we've got Southwest ramp and then we'll call this southeast ramp the reason I'm being so careful about naming is because if you bring a bunch of different roads into into civil3d it becomes easy their name just by number and it becomes really easy to pick them out then when you see actually see the names so all I'm going to do now is now you can go into infraworks and say open in four works model and actually you know browse to the sequel Lite file and all that I actually prefer even though it works just as well to just export in IMX out of out of info in for works like this so I'm going to export in IMX of my my design give it a place to go you can see I've got one here already called Turnpike connector I'll just call this Turnpike connector too and I'll hit export notice my my coordinate system PA 83 South foot and then I've got a civil 3d drawing over here give that a second to export and I'll go to my insert tab open in for works model now by default it will want to browse for a sequel Lite file but because I've done this before and picked IMX it's going to default to the IMX format okay so I'm just going to grab this ultra grab number two since that's the one we just created click uh I want to refine my selection set I don't want to bring in everything in the box that I created so all my dialogues are on a different screen today so I'm not going to bring in any terrain surfaces except infraworks existing ground I don't want any planning roads and as far as design roads go I only want I'm not sure what that one is but I only want my my ramps and my Turnpike connector and I'm going to go ahead and bring in intersections as well because I may want to use some of that intersection geometry when I'm actually building intersections notice also our one bridge is is here and by the way that's another reason why I changed the style or the the makeup of the Turnpike Road to one Road is because it's a lot easier to make a bridge under a single than two parallel roads so go ahead and hit open model and that stuff's going to jump in and now you can see all my alignment geometry you can see the bridge take a look at that in 3d it's very nice and then I you know the alignment and profile information is all here so for example if I wanted to see a profile view of my Turnpike connector I can go ahead and create that and there's the profile view and I could begin my detail design from here you know tweaking the profile you know defining the intersections getting all that exactly defined the way I want it and moving on to you know documentation as well plan in profile sheets all that stuff so that's the beauty of being able to move this data from from infraworks to civil3d so readily so I'm about out of time what I'll do is I'll switch back to my powerpoint here and remind you guys that and I want to make sure I hit all my bullet points so let me check that real quick at least talk about one if I missed it yeah we covered widening ramps and overpasses I didn't do custom road side elements so let's do that really quick so a good place for a custom road side element would maybe be this curve right here that looks like a pretty sharp curve we don't want someone taking that too fast end up hitting oncoming traffic down here so I'm going to click the road and right click and insert decoration or place decoration and we've got these really handy parametric objects up here so and to get to the parametric models you know you're probably going to be set to maybe this 3d models or both of them just filter out 3d models and now all I see are parametric models so now I can pick this really handy dandy guardrail here drop that in and what's nice about these is they're customizable so you know right now it's saying my the length of the rail I think it's ten feet something like that the spacing is 32 feet that's why they're so far apart I'm going to bump this down to eight I'm going to tell it and I'm doing this really quick because I'm because I'm out of time here and to tell it I want to tilt tilt them so they match up nicely and maybe because it's such a sharp curve I'll do them a little a little shorter so right now the length is eight let's go to four feet with a spacing of four feet and because this is such a sharp curve and you know heavily traveled area I want to have you know more than more than one rail so I'm gonna make this three rails so that's just one example of the custom roadside elements that you can build and if I'm going to need three rails I'm going to need a taller post as well which I have the control over that too alright so that covers all of all of the bullet points that I had in the description for you just a final reminder that our next webcast will be on April 18th from 12:00 to 1:00 we'll be hearing from Dave and Sarah about what's new in civil 3d and in four works I want to thank you all for giving me and Elliott an hour of your time today I hope you picked up lots of good tips and tricks and good ideas about how you could leverage the roadway design tools and in four works and now we hope to see you again in two weeks for for the what's new web cast it's going to be really exciting to hear the news about about what's coming thanks again and enjoy the rest of your week
