I am doing some lot grading and in a couple of areas of the lot grading I run into a situation where lots that are back to back require a wall because the backyards of the lots would require a grade steeper than 3:1. So we have to put walls in the back of the lots to limit the grade to 3:1 on both sides of the wall. My question is how would you do that when you are working with the grading creation tools? I attached image of what I have so far. The green linework is proposed contours (lot grading) and you could also see the grading objects linework. The white line represents where I want to put the wall. Any help, suggestions, or different methods I will gladly welcome and be thankful for.

I like profiles for larger walls...
Make an alignment for bottom of wall and another for top of wall. Sample surface profiles for each.
Use the superimpose profile command to place them in one profile view so you can now use layout profiles to define FG condition on the wall.
Create a corridor with only a marked point assembly on each layout profile.
Extract feature lines from the corridor and either place them in the required surface or create a surface for the wall and paste this into a composite FG surface.

You can also model the top face of wall with a generic link with and slope subassembly. Just set the width for a single block and attach it to the top of wall assembly. Be careful the top inside edge does not extend over the bottom of wall alignment. The 3 feature lines (bottom of wall, top inside and top back edges) will make a nice model for profiles or sections.

The marked point is what allows the feature lines to be created. No marked point, no feature lines.
Try it. 🙂

John just one question about the first method you told me. Would the create feature lines from alignment command have the same end result as the method you told me to create a mark point assembly and run it on the top and bottom wall alignment and then just extract the feature lines from the corridors?

Create a corridor with only a marked point assembly on each layout profile.
Does each MP attach to the assembly node and be named accordingly?
