What problem does it solve?
Custom subassemblies solve the need to create reusable, parameterized geometry for Civil 3D corridors by letting developers implement .NET classes that generate subassembly geometry via the SATemplate pattern and SubassemblyGenerator.
Core Features & Use Cases
- Define cross-sectional shapes using the SATemplate pattern for reusable, well-structured subassemblies.
- Configure SubassemblyGenerator to load a compiled .NET assembly and a fully qualified class name to produce geometry.
- Support reliable naming conventions, parameter types (Widths, Offsets, Slopes), and target mappings (Surface, Alignment, Profile).
- Handle superelevation scenarios and common design challenges (pivot points, PGL relationships) within corridor workflows.
- Example components: LaneBasic, ShoulderExtended, CurbTypeA; incorporate Utilities and CodesSpecific for consistency.
- Best practices include robust error handling via corridorState.RecordError() and adherence to the SATemplate workflow.
Quick Start
Compile a first custom subassembly by implementing a .NET class following the SATemplate pattern and wire it to a SubassemblyGenerator instance for testing in Civil 3D.
