Simplifying Civil 3D Corridor Modeling using Contextual Tools

in this session we'll explore some civil3d corridor modeling shortcuts using the contextual tools found in the interface let's take a look now most civil3d courses will teach students to create and edit corridor designs using the corridor properties dialog box as an example I'm going to select this corridor and from the ribbon I'll choose corridor properties this dialog box represents a one-stop shop to do everything from creating base lines and surfaces to assigning frequencies and targets in fact if you right-click on some of these items you'll find additional tools for adding removing and splitting corridor components having said that if this is the only tool you use for corridor modeling you'll find that as your models become larger and more complex so also does this dialog box which may lead to confusion for yourself or others when editing a proposed design today we'll look at some alternative ways to model corridor geometry that do not require us to jump in and out of this dialog box I'm going to click cancel to close this and I'll press escape for my example I have the beginnings of a simple intersection design at a high level I've got an existing ground surface called eg I have a pair of intersecting alignments one is called Summit Street and the other is called Barrington Avenue each of these alignments has a corresponding finished grade profile I have also created offset alignments and profiles representing the edge of pavement for both roads and I've defined to curb return alignments and profiles to tie all this geometry together if you're wondering how all of these items were created down in the description I'll leave a link to a video that walks through that process over here to the right we can see the Assemblies that we'll be using I've got one that represents a full pavement section with daylight's I've got another that represents a road section and daylight however it does not have the curb and gutter or daylight on the right side this is the assembly we'll use in the intersection itself I also have an assembly that represents the curb return areas let's zoom out we'll pan this over currently Barrington Avenue is using the full pavement section for the entire length of the alignment now this assembly is perfect until such time as I get to the curb return in this area I don't need the curb and gutter or the daylight so I would like to swap my assembly in this area I'll start by splitting the corridor model we'll do that by selecting the corridor then instead of going into the corridor properties take a look at all of these tools that we have in the contextual ribbon tools for both modifying the regions and the corridor itself virtually everything we can do using the corridor properties dialog box we can also do from here I'm gonna choose split region I will then click inside my desired region and I would like to split this at the end point of the return I will then click inside this new region to the left and I would like to split this one at the end point of the other return I'll press Enter when finished now to swap out the assembly I'm going to expand the modify region panel and from here I'll choose region properties before I click on this take a look at some of the other tools that are available in this panel when you get a chance come back and explore some of these other options after choosing region properties I'll click inside the center region from here I can see and edit its properties I'm going to click in the assembly property and then I'll click the ellipsis button and we'll choose the no curb gutter right assembly I'll click OK and ok that's perfect let's zoom out next I'd like to add a baseline for Summit Street I'm going to come back to the ribbon and I'll choose add baseline right here I can give the baseline a name I can select its type alignment and profile is perfect in this case using the menu I can select my desired alignment I'll choose Summit Street and then I'll click OK I can then choose the corresponding finished grade profile for that centerline alignment and I'll click OK once the baselines been defined we can add a region let's come back to the ribbon I'll choose add regions I will then click next to the baseline that I'm interested in I will add the region from the end of the curb return down to the end of the alignment I'd like to use the full section let's click OK I'd like the assembly to daylight to the existing ground surface I'll click OK from a horizontal or vertical perspective I don't need to assign any targets for the lanes or the daylights so I'll just click OK this looks good I'll press escape to jump out of that command next we'll add a baseline for the Northeast return I'll come back to the ribbon and choose add baseline now maybe I don't know the name of that alignment don't have to if I click the green block I can select this graphically from ringg you can see it's the Northeast return let's click OK I will then select the corresponding finished grade profile for that alignment and once the baseline has been defined I can then add another region now I could do that from the ribbon or if I right click I'll find many of the corridor modeling tools I need right here in fact I have more tools in this menu that I have space on screen when you get a chance come back and explore these options as well you may be surprised at what you'll find I'm going to choose add regions I'll then click next to the curb return baseline I'd like to start the region at the beginning of and then go to the end of the curb return we will then select the returns assembly and I'll click OK I would like that to daylight to the existing ground surface and then as the sweeps around I would like the lane to follow the right side edge of pavement of Barrington Avenue and then I'd like it to follow the center line of Summit Street so from a horizontal targeting perspective let's follow the Barrington right side edge of pavement and we will follow the Summit Street centerline whichever's nearest I'll click OK and then from a vertical perspective I would like that to follow the Barrington right edge of pavement finished grade profile and I'd like it to follow the summit Street finished grade centerline profile whichever's nearest I'll click OK and ok this looks good they press escape to jump out of that command you can see how that assembly is sweeping around the bend the only thing I need to do now is adjust the frequency in this area and I'd like to add an assembly insertion here at the corner if I select the corridor I can come up and edit the frequency from the ribbon or if I right-click I can get that option right here I'll click inside my desired region let's increase the assembly insertions around the curve to every 5 feet and then I would like to add an assembly insertion at the shifter I click a parent intersection of the alignments and this edge of pavement feature line I'll press Enter and click OK to accept let's zoom out this looks good finally we can finish things up by adding another baseline I'll click the green block and we'll select the northwest curb return and it's corresponding finished grade profile I can then come right up and add a region I'll click near the baseline and we'll run that region from the beginning to the end of the curb return I'll select their returns assembly and click okay we'd like that to daylight to the existing ground surface and I'd like the lane horizontally to follow the Barrington right edge of pavement alignments and any Summit Street centerline alignment vertically I'd like that Lane to follow the Barrington right edge of pavement finished grade profile and the Summit Street centerline finished great profile I'll click OK and ok last thing will adjust the frequency I'll click at it frequency and will click inside this region will tighten up the assembly insertions around the bend to every five feet and then I will add an assembly insertion here at the endpoint of this other assembly insertion I'll press ENTER and okay that looks great I may press escape to jump out of the command my corridor is still selected I'm going to come up to object viewer and we'll click the southeast hotspot here a couple times to center that on-screen and then I can zoom in and we can orbit this around and take a look so the next time you're working on a civil 3d corridor model try using some of the contextual tools provided in the interface with a little practice you can eliminate many of those trips to the corridor properties dialog box and take your corridor modeling skills to a whole new level would you like to explore other Autodesk infrastructure ideas and workflows if so please visit the civil immersion
