: Build components that automatically adjust to targets like surfaces, offsets, and profiles.
The Subassembly Composer is a standalone application included with Autodesk Civil 3D. It allows engineers and BIM technicians to visual-program custom components (like complex curbs, retaining walls, tunnels, or ditches) without needing advanced .NET coding skills. Why Use Subassembly Composer?
Drag an into your flowchart.
Always prefix points (e.g., P1, P2) and links (L1, L2) logically.
Create parametric components that adapt dynamically to target surfaces, offsets, and profiles. civil 3d subassembly composer tutorial pdf
To move beyond basic designs, you need to understand the core building blocks of Subassembly Composer:
Add a final link closing P6 back to P5 to seal the shape geometry. Step 6: Define the Material Shape ( : Build components that automatically adjust to targets
The control center for variables. Here, you define user-input parameters (e.g., Lane Width, Pavement Thickness) and Target Parameters (Surfaces, Offsets, and Profiles). Properties Panel
These define the dimensions that users can modify manually within the Civil 3D Properties palette. Why Use Subassembly Composer
