1. Open Civil 3D and press F1 to generate the official help PDF.
2. Search for "AUGI Subassembly Composer Workbook PDF" (often freely available to members).
3. Build the "Trench" example above. Once it works, modify it to include a SideSlope parameter.
4. Keep the PDF open on a second monitor. Every time you find yourself manually editing corridor links, stop. Ask: Could I automate this with a custom subassembly?
