This PDF guide is designed to take you from "Zero to Hero" by breaking down the workflow into digestible steps. Here is what you will learn:
Save your work as a .pkt file. Before moving to Civil 3D, test it thoroughly using the Preview panel's different modes to ensure the geometry behaves correctly with various inputs.
In the condition box, write an expression comparing a point to the surface target, such as: P3.DistanceToSurface(ExistingGround) < 0 .
I’ve found a great resource to help bridge the gap. 📉📈 civil 3d subassembly composer tutorial pdf
