Dats da one.
Maybe I'm reading too much between the lines but I steer clear.
In my earlier experience I used a BasiCurb and because it has no offset on the face I believe it caused corruption in my TIN, at the time.
I too stear clear of the basic subassemblies. Why? Well, I remember them causing issues several releases ago. What where those issues? I honestly don't remember.
If the only reason you are doing something is because that's the way you've always done it, you're doing it wrong.
Perhaps I should go revisit the basic subs and see if they still cause issues or not.
Instead of a Basic Lane, use a UrbanSidewalk with a 0' inside width, 2' walk, 0' outside width. Attach the ret.wall to this, the sidewalk width can be set to a target.
Yep that worked Jeff. The only thing I ran into was, I put the "shape trapezoidal" sub-assembly under the sidewalk and in my section where the urban sidewalk was gone because the wall took its place, the shape trapezoidal sub-assembly moved up in the place of the sidewalk. I didn't get this at first but when I targeted that sub-assembly to the same target lines as my sidewalk was targeted to, the shape trapeaoidal sub-assmbly went away also. Make sense? Kinda wordy but I think it doing what I need it to.
Your absolutley right Fred; they would never put anything in the program that would screw things up
