Drag another into the flowchart, connecting it to P1. This creates P2 .
Always validate your subassembly by changing values in the Preview panel before importing the asset into production drawings. civil 3d subassembly composer tutorial pdf
The Subassembly Composer allows users to build custom components for corridor modeling without knowledge of .NET programming. It utilizes a flowchart-based logic system to define points, links, and shapes. Packet Settings: Defines the subassembly name and image. Drag another into the flowchart, connecting it to P1
Drag a second below P1 . It defaults to P2 and automatically creates Link L1 . Change the Point Geometry Type to Slope and Delta X . Set From Point to P1 . Set Slope to GutterSlope . Set Delta X to GutterWidth . Add Codes: Point Code = "Gutter" ; Link Code = "Top" . Step 4: Create the Curb Face ( Drag a third Point below P2 . This creates P3 and Link L2 . Change Point Geometry Type to Delta X and Delta Y . Set From Point to P2 . Set Delta X to 0 (vertical line). Set Delta Y to CurbHeight . Add Codes: Point Code = "CurbTop" ; Link Code = "Top" . Step 5: Complete the Structural Loop ( Follow the same logic to close out the perimeter: The Subassembly Composer allows users to build custom
The tab where you define variables (like "Lane Width" or "Pave Depth") that users can change inside Civil 3D. 2. Setting Up Your Parameters
: Enables daylighting (intercepting an existing ground surface). Use the Intersection geometry tool to calculate where a link hits a surface target.
