To start, launch the Subassembly Composer from the Autodesk Civil 3D menu. You can also access the software from the Windows Start menu.

Forgetting quotation marks around codes (e.g., writing Top instead of "Top" ) is the number one cause of corridor surface generation errors in Civil 3D. Create another parameter named GutterWidth , type ,

To demonstrate the core functionality of Subassembly Composer, we will build a custom ditch subassembly featuring a variable bottom width, a parametric depth, and conditional daylighting logic. Step 1: Establish the Origin (P1)

Community-uploaded guides that offer quick-start workflows for creating static and dynamic subassemblies. Core Learning Components Delta X = 0, Delta Y = CurbHeight

Real-world designs require conditional logic. For example, if a road is in a "Cut" scenario, it needs a ditch. If it is in a "Fill" scenario, it needs a daylight slope to the existing ground.

Assign a code like "Pave1" to ensure material quantities calculate accurately. 4. Advanced Logic: Decisions and Switches
