Modelling Bridge Abutments in Civil 3D

[conrado.gallardo]

Does anybody knows which is the easiest way to model bridge abutments in Civil 3D?

I doubt my method is the best way, but I would do it by drawing a 3D wireframe model of the abutment(s). It wouldn't be dynamic. I avoid feature lines and use 3DPOLY's so that I don't have them interacting with each other. I avoid vertical faces by introducing a slight horizontal offset where it is supposedly vertical. After I get the model how I want it I create a surface.

But someone probably knows how to do it with a corridor or something.

Is using Infraworks to model abutments an option?

InfraWorks to C3D can get you a good approximation of the abutment. It depends on how much control you need over it. If you want to fully customize it, it might be better to custom model it.

It's because there are certain parameters that resist modification, like the bearing shelf slope.

Ideally you would model it in a true parametric modeler like Inventor and then export/import the solid into civil 3d to place on various views, but you can model it directly in AutoCAD/Civil3D too, if you don't mind taking longer to make adjustments.
