The Subassembly Composer is an intuitive authoring tool designed to tackle complex grading challenges, detailed construction plans, and accurate quantity take-offs. Instead of writing code (like .NET), you use a flowchart-based interface to define how your road lane, shoulder, ditch, or curb behaves based on targets (surfaces, alignments, or offsets).
Once your subassembly is constructed and saved as a .pkt file, follow these steps to deploy it: Open Autodesk Civil 3D. Open your ( Ctrl + 3 ).
Use "Switch" node for 3+ conditions (e.g., shallow fill, moderate fill, cut). While you won't find a single official PDF
Custom shapes can dynamically stretch, target specific surfaces, align with feature lines, or snap to property offsets. 2. Understanding the SAC Interface

Build "logic" into your parts (e.g., "if the fill height is > 5ft, use a specific slope").
