Create a Graded Path Over a Steep Terrain in Revit® | Revit Workflow for Landscape Architects

Hi everyone this is Nechama from Arch-Intelligence  and welcome to another grading tutorial where I'll   show you how I created a graded path that connects  this Villa and the stairs leading to the beach   um so let's get started all right so moving to a  plan view I would not go too deep into the site   engineering part of things it's very simple I  already did the calculation of how I want the   path to look like and what I want the overall  slope to be so you can see here that in this   detail line I kind of created the center line of  the path I calculated the approximate length that   I want it to be and using the environment total  length option I was able to make sure that this   Center Line really gives me the overall length  of the path that I wanted to have and then I   calculated the start and end elevation to get  the rise of the path so that's how I made this   calculation the next step and there are a lot  of different methods that I could create these   um graded path for this situation since  I wanted to be very accurate I chose to   do it using model lines as contour  lines and to create a help surface   from that to drape the flat floor that  you can see here in the background so I wanted to place model lines in equal  distances along this path and I want to   leverage the line scatter command to be able to  place them and do that but it doesn't work with   model lines so take a look at this family that  I created that's the most simple family if I   go to the edit family option you can see that  these families simply contains one model line   that would be hosted on my Surface so I'm going  to use that to understand how the contour lines   should be spread out across or across my Center  Line let's open the line scatter option use the   draw path option and with the peak lines tool  I'm just going to tab select my Center Line   as simple as that now let's click on apply  path over here and make sure to use the   combine elements option I want the distance  between my contour lines to be approximately 3.7 now just to explain um the the vertical distance  between each of my contour lines that I'm planning   is going to be 25 centimeters and to get the  correct slope I'm just going to place them in   3.7 meter distance between them so that's what  I'm doing right now with the line scatter tool   so once again I'm going to use the combine  elements open option to make an assembly out   of them let's click on apply and then you can  already see them set let's use the rotate with   lines to so I will make sure that these lines  would kind of move with my center line now pay   attention water runs perpendicular to these  contour lines and I want to have a side slope   and I want the water to run kind of to the sides  of my path to achieve that I'm going to change   the rotation angle of these lines I think  it would be 170 degrees now let's do it 160. yeah and click apply to see the result yeah so  now I'm happy because you see the water would   run perpendicular to my lines they're going to  go off the path and not go on it as if it was   a river so now that I'm happy with the result  I'm just going to click on finish scatter now   remember this is just here for me to use when I  draw my real model lines which I will do right now   so first I have a line style that's dedicated  to be used for helplines before I will use   the model line command over here I would  actually go to the visibility Graphics menu   go to the line category and  turn on my helplines line Style now I'm going to go to the  model line command and use   the pick line to pick all these lines  and draw model lines in their place all right so um now that I'm done let  me just uh hide the Assembly of families   and also hide the topography just to have a clear  view of my model lines over right here so the next   step would be to use the environment set elevation  command to give them an elevation here's my start   value 13.50 I want to start 25 centimeters  under that so I'm going to click on 13.25   and the increments of the vertical  distance between the line would be   negative 25 centimeters let's  use set elevation by Crossing   and I'm just going to fast forward as I'm crossing  on the lines and assigning elevation to them all right so you see I have a text label  on top of every line I'm going to delete   the last line over here because I don't  need it I want the slope to go straight   from 750 to the end all right that's just  how I design this thing let's move to 3D   view take a look at the lines you can already  imagine the shape of my path so using these   model lines I want to create a help surface  that I would shape the flat floor according   to let me just adjust some of these model  lines to make the help surface big enough and now that I'm ready now that my model  lines are perfectly ready I'm going to use   the environment topography tools to create the  help surface so let's select the add line command   and simply window select all my model eyes  I can leave it like that you can see the   elevation points here but I actually  want to use the custom setting option   to kind of place more elevation points on each  line that would give me more accuracy click on add   line once I'm happy and now I will use the from  Edge tool to just select the start and end edges   of the path click on insert points and finish  once I'm happy so again this is a help surface   that would allow me to drape my flat floor on  top of it let's use the slope Arrow to just make   sure that we're in the correct slope and yes I'm  quite happy with the result that I achieved here now let's isolate the help surface  and the floor that we want to drape   according to it I want to isolate them in  the view since I really want to make sure   that my help surface really covers every part  of this flat floor you can see over here that   I have a few edges that are not really covered  by the help surface so let's go to topography   tools and this time I'm just going to select  a point and move it to stretch my Surface so now that I'm happy um let's select both of them  environment and shape by topography command that   would actually automate the process of modify  a sub element and it would just drape my floor   according to the help surface okay so now that  the command is done you can see that there's just   one point that remained you know in zero elevation  let's unhide everything and select the floor go to   modify sub element that probably because the help  surface didn't cover a specific point so I will   just select this point with the modify sub element  option and drag it until it snaps to its place perfect so now I'm pretty happy with the result I  can just hide this help surface I'm simply using a   view filter you can use any other methods to hide  it hiding these model lines would not be so hard   since every line style behaves as a subcategory  so I could just use hide in view by category   let me also delete the Assembly of families I  don't need it anymore and do the same in the plan   view just delete the extra elements uh to clean  my view really delete or hide in view by category   Let's uh unhide the surface and no I don't want  to save right now see the result so just to make   this view uh prepared for documentation  let's go to the slab Contours option   and click on finish after selecting the path and  add contour lines every 25 centimeters to make   sure that this path is good and also I can use  the check elevation by Crossing option to add   um Contour labels on the contour lines on my path let's move back to 3D View and now that I  finished the first part I want to grade this path   in a specific slope to grade it to the existing  surface so to do that I would create a totally   new topography that would go from the bottom  face of my Surface and it would also allow   me to see the earthwork calculation and  start creating our new graded surface   I'm going to go to environment topography tools  again this time I will use the peak face tool   to create a surface from the bottom face of  my floor over here let's click on it once   and immediately environment would  select the entire bottom face of my path   let's click on insert point and now I will  actually move to a plan view to start the   grading process to grade it to the existing  topography let's move to plan View and use   the slope path tool for this one so the slow  path tool works by selecting the first point   stretching a direction clicking again to create  another point and then I can either slope it by   starting and elevation or by giving it a slow  percentage and again this would work with any   units you work with I want to go with negative 50  percent and I'm going to stretch these negative   50 slope a few times in both sides of my  path let me fast forward as I'm doing that okay so now I have a new topography that's  graded uh downwards towards the existing   surface I didn't finish yet but let's click on  finish and give it a different material let's   say grass and it allows me to see the exact line  where the existing and new topography are meeting   but you see that the surface is not quite  good yet so I'm going to click on it again   and use the topography tools to  adjust it just a little farther   uh this time I want to use the insert midpoint  tool which just adds elevation points in between   two existing points so it adds information  between existing points without really changing   the original slope that I meant to have I would  actually move to a plan view right now because   then I can see even the elevation points that are  under the existing line and pay attention how I   use the insert midpoint to kind of smooth  out the topography and make you know the   um the way the new topography meets the  existing topography I want to make it a   little bit smoother so I'm just going to run these  uh insert midpoint a few more times over here all right so now I'm pretty happy with the  result you can see how accurately I can see   where the new topography meets the existing one  the last stage would be to split it and in order   to understand where to split it I'm going  to use a detail line let's use dashed violet   and I'm gonna fast forward as I'm just marking to  myself where the new topography should be split so this detail line would also show me  where it will make it very clear where   the the split line is it will also allow  me to use the messing inside split surface   option and I would just use the  pick line tool over here as well all right now that they're all selected I  can go ahead and click on the green tick   to approve this bleeding process and simply  delete the extra part of the new topography   that's it that's the entire process let's move  to a 3D view you can see that since I have an   existing topography in my file once I select  this one I can already get the cut and fill   the earthwork earthwork calculation for this  path over here you can see how I created a new   sheet from that I've added a few section views  that can really show me the differences between   the existing and new topography and that's  it for the graded path tutorial I hope you   enjoyed this one and if
