Hints for corridor with retaning wall

[normans]

Hi all,

Looking for suggestions:

Am designing drieway on steep hillside. Would like to include option for a retaining wall on the upslope side to reduce the amount of cut. I have had a little luck using the ret wall assy from acad. The missing part is how to control the wall height. Right now my corridor looks good but with 10 - 11" wall. I would like to control the wall height to about 4 feet.

I believe one way is to extact a feature line from my corridor and use that as target for the wall height. This is stated in the help for the sub-assy. I assume the flow would be to extract the ETW f-line and raise it to the desired wall height and then use that as the target for the wall. Haven't discovered how to assign the ext. line as target yet, but I'm digging out the book! Thanks in advance. Newbie!

One way to tackle this is to use a conditional cut/fill assembly. If the end point is in cut>4' add a wall subassembly with a fixed height of 4'. If you want a benched wall you can repeat the cut/fill conditional and add a bench then another wall.  Repeat until Cut<4'

Thank you for the suggestion. I will see if I can make that work.
