Civil Design 3d - Subassembly Composer Tutorial Pdf Top
Auxiliary elements are construction lines that calculate tracking vectors behind the scenes. They look like dashed gray lines and are completely invisible inside Civil 3D once compiled.
Your custom subassembly is now ready to be deployed on any corridor assembly baseline!

By mastering the Subassembly Composer, you elevate your Civil 3D capabilities from standard modeling to fully customized, intelligent engineering design. If you're interested, I can: This public link is valid for 7 days
If the vertical distance from P2 to your terrain surface exceeds 3 meters (a deep cut scenario), the flowchart takes the branch where you can program a safety bench.
Define structural offsets below P1 and P2 (e.g., P6 and P7) using Delta X and Delta Y to represent structural pavement depths. Add a component from your Toolbox to the flowchart. Can’t copy the link right now
Name it CurbHeight , set the type to , and give it a default value of 0.150 (meters).
This panel houses the building blocks of your subassembly. You will drag and drop items from here into your flowchart: Points, Links, and Shapes.
Instead of entering a raw number in the Delta X box, type your parameter name: LaneWidth . In the Slope box, type your parameter name: LaneSlope .
To accelerate your learning, studying real-world examples is invaluable. Sample PKT files are available for download from the and are often included with your Civil 3D installation. You can find installed sample subassemblies in a folder path similar to: C:\ProgramData\Autodesk\C3D 20xx\enu\Subassemblies\Metric . Opening these complex files in SAC is a great way to see how advanced features like loops, switches, and API functions are structured.
