Civil 3d Subassembly Composer Tutorial Pdf

For your custom subassembly to work correctly in Civil 3D, you must assign . Point Codes: "Pave", "Curb", "Hinge". Link Codes: "Top", "Datum", "Pave1".

Set to P2 . Set Delta X to 0 and Delta Y to -PaveDepth . Check Create Line ( L2 ). Drag another Point (P4) under P3. Set From Point to P1 .

To understand how these blocks fit together, let us build a standard parametric curb and gutter assembly.

Ensure you use the native Side parameter loop system in Subassembly Composer expressions rather than hardcoding left or right offsets.

Set Delta X to 0 and Delta Y to -PaveDepth . Check ( L3 connects P3 to P4). civil 3d subassembly composer tutorial pdf

To give you an idea of how a tutorial operates, here is a high-level overview of the workflow you will follow when building a simple custom curb and gutter:

Drag a tool into your Flowchart below your point definitions. Click the Shape component in the flowchart.

In the P2 properties, set to Slope and Delta X . Set From Point to P1 .

On the left, you'll see tools to define points, links, and shapes. For your custom subassembly to work correctly in

: Start a new project and set the subassembly name in the Packet Settings. Define Parameters

If you want the shoulder to daylight to a surface, add a parameter:

The official Autodesk Help site provides comprehensive, downloadable documentation on SAC fundamentals. Set to P2

Contains the building blocks (Points, Lines, Shapes, Decisions, and Switches) that you drag and drop into your design.

Autodesk Civil 3D’s Subassembly Composer (SAC) is a powerful tool that allows engineers and designers to create custom subassemblies for corridor modeling. While Civil 3D includes a library of standard subassemblies, real-world projects often require unique pavement structures, ditch shapes, or retaining wall configurations. This tutorial will walk you through the basics of SAC and guide you in creating your first custom subassembly.
