Creating a simple retainning wall?

[sonny_morales]

I am trying to create a basic retaining wall in sub assembly composer but cannot seem to figure out how to make it step and also how to make it slope to eg.

this is the plan view of where it would be, at the north it will be about a 10' high wall, and towards the south it would be about 4'. 

Can i create a subassembly that just has the bottom of wall make that slope? Would it have to be tied to a design profile?

Once that is made i need to have the bottom of the wall just slope out to eg.

I have tried to do this but cant seem to figure out how to make the surface i create from the corridor, look how i want it to, if that makes sense.

Looking for a little guidance as I am getting close to my deadline for this project.

Thanks
Sonny

Hi @sonny_morales, I hope you're doing fine. I read your post thoroughly, but I didn't get it. Could you please explain to us the behavior you are talking about with a section view on both the part where it has to be 4 high and the part where it has to be 10 high?

Best regards!

I often use corridors to build my retaining walls, here is my workflow.

1. Draw alignment along base of wall or top of wall, whichever is more important
2. Create surface profile (longsection)
3. Draw profile for desired top of wall / base of wall levels, or both.
4. Create assembly using LinkSlopeVerticalDeflection, set slope to 1908 (87 degrees).  Add LinkSlopetoSurface if you want the wall to daylight 
5. Create corridor, using assembly as above.  Use base profile (or EG) as your baseline, set LinkSlopeVerticalDeflection vertical deflection target to your top of wall profile.
6. Generate surface from corridor, using toplinks and corridor extents as outer boundary.
7. Paste retaining wall corridor surface onto your proposed surface.  If you have multiple walls I'd recommend pasting them into a "combined walls" surface and then pasting that into your proposed surface.

Ok so i am a little confused at the assembly part of this. I have a feature that dictates the top elevations of wall, i created an alignment and surface profile to delineate the proposed bottom of wall. How do i use "LinkSlopeAndVerticalDeflection" to go downward from attachment point, which i am assuming would be my top of wall baseline. Correct?

If you are modelling your wall with a corridor (which is my preferred method), you don't need to use a feature line. Draw a profile in your longsection for your top of wall. You can project your feature line onto your longsection and trace it if that helps.

I assume your alignment is at the base of the wall, not the top of wall?

[sonny_morales]

correct, I was trying to use an alignment along the wall and create a surface profile of the EG, then create a design profile of what i want the base of wall to look like and use a feature line for top of wall. I will have to play around with this and see how it works, I think once i project my top of wall into profile i will get a better understanding of it.

I have made an example drawing for you to check out, see attached:

Make sure you include a batter angle :triangular_ruler: if your wall product has one (typical)
