Here are some top resources to help you learn Civil Design 3D Subassembly Composer:

Connect points to create the linear components of the subassembly.

For geometric calculations beyond what the basic toolbox provides, you can tap into Visual Basic (VB) expressions within the Subassembly Composer. The API functions are documented in the Autodesk help system and give you access to powerful mathematical operations, conditional logic, and geometry calculations. Common VB functions used in SAC include Math.Sqrt , Math.Pow , string operations, and surface interrogation methods like Surface.ElevationAt .

The core philosophy of Subassembly Composer is to make custom subassembly authoring accessible to all Civil 3D users. Instead of writing code, you build logic using a drag-and-drop flowchart that defines geometry, conditional behaviors, and dynamic targeting. When you need a subassembly that doesn't exist in the Civil 3D tool palette, SAC empowers you to create exactly what your design requires. civil design 3d subassembly composer tutorial pdf top

Define geometry using slopes, offsets, or intersections. Here are some top resources to help you

Setup configurations for Surface targets, Elevation targets, and Offset targets.

Subassembly Composer solves this issue. It is a standalone visual programming interface where you can build custom parts without needing advanced .NET programming knowledge. Why Use Subassembly Composer?

Follow this universal sequence to build any custom asset without errors. Common VB functions used in SAC include Math

Once your logic is flawless, save your project as a . This is the native format for Subassembly Composer. Importing to Civil 3D Open your Civil 3D tool palette.

Input parameters allow users to change dimensions directly inside Civil 3D properties. Create parameters for variable widths, depths, and slopes. Use clear naming conventions like Lane_Width or Curb_Height . Target Parameters
