In this video, we show how to create a Retaining Wall subassembly in Subassembly Composer for Civil 3D corridors.
You will learn:
✔ How to open Subassembly Composer in Civil 3D
✔ How to define input parameters for retaining walls (height, width, slope)
✔ How to draw wall geometry using Shapes tab
✔ How to assign targets to tie the wall to corridor surfaces
✔ How to connect the wall subassembly to corridor baseline
✔ How to export and test your wall in a Civil 3D corridor
✔ Tips for site execution and quantity calculation
This tutorial is very useful for:
Civil Engineers
Site Engineers
Surveyors
Civil 3D Beginners & Students
Road, Highway, and Infrastructure Project Staff
Understanding how to create retaining wall subassemblies is essential for road alignment, embankment stabilization, and corridor modeling.
