All subassemblies follow a foundational hierarchy:
Always establish your subassembly parameters before building any geometry. Navigate to the tab and define:
: This is your main workspace. You drag, drop, and connect geometric components here to define the logic of your subassembly from top to bottom. civil design 3d subassembly composer tutorial pdf top
Select L1 and add "Top" and "Pave" to its Link Codes. These codes allow Civil 3D to build top-pavement profiles and datum surfaces. Step 4: Closing the Geometry and Defining Shapes
To create a structural layer (like asphalt or concrete aggregate), continue adding points (P3, P4) downwards to define the thickness of the material. Connect the final link back to P1. Drag the tool into the Flowchart. Select L1 and add "Top" and "Pave" to its Link Codes
: Located at the bottom. This is where you define input/output variables, target parameters (surfaces, offsets, elevations), and superelevation properties.
For those looking to master for Civil 3D, there isn't one single "top" PDF; instead, the most effective resources are highly practical, step-by-step guides that focus on logic over just geometry.
