Check the option. This instantly draws L1 between P1 and P2 . Step 3: Add Code Names
Before designing, users must familiarize themselves with the SAC interface :
Assign a code like "Pave1" to ensure material quantities calculate accurately. 4. Advanced Logic: Decisions and Switches
Every subassembly begins at the Origin point P1 (0,0). This point attaches directly to your Civil 3D assembly baseline. Step 2: Create Relative Points To build a standard road surface link: civil design 3d subassembly composer tutorial pdf top
: Force points to follow alignments, feature lines, or survey figures.

By following the tutorial PDF and tips provided in this article, users can become proficient in using Civil Design 3D Subassembly Composer and start creating their own 3D models of road and highway designs. Check the option
To make your subassembly dynamic in real-world scenarios, you must implement targets and logic gates. Surface Targets (Daylighting) To make a ditch or slope find the existing ground:
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.
Add Links connecting Points; define link types and materials. Step 2: Create Relative Points To build a
Name your points, links, and shapes logically (e.g., P_TopLeft , L_TopLink ). It makes debugging significantly faster.
Under the branch, build a fallback geometry (like a fixed extended slope) in case the surface target isn't found in Civil 3D. Cut vs. Fill Conditional Logic To determine if your assembly is above or below ground:
