how to model counterfort retaining wall in civil 3d

[xiaogh98]

Do you know how to implement the counterfort part in modeling a counterfort retaining wall taking advantage of corridor or give me some advice.

Maybe the point is how implementing the subassembly in subassembly composer.

Thanks very much.

this can be done by using the normal autocad 3D functions. Draw the counterforts and extrude it to the thickness that is needed and place them on the correct positions, or you can create a sub-assembly with the counterfort in it and then apply it to specific regions only, its allot of working dong it that way but can be done

thanks very much,
The difficulty for me is "apply it to specific regions", how to define the "specific region" where there are counterforts, equally spanned is a choice but it cannot comply the real scenario.

Do you know some example subassembly like the "counterfort" part?

thanks again.

[Domziman]

you can manually create the subassembly in subassembly composer, or Civil 3D has a function where you can create subassemblies from polylines

Dynamo ships with a counterfort wall example in the samples section.

But how to use it ?? Can somebody explain it, please? Also if I want to make it from a subassembly composer how is it possible ?? All I can do but I don't know how to create it in 3D space i.e. Z direction assembly. And also how to maintain the interval of structure?
