Your custom asset is now natively accessible. Clicking it allows you to view and alter all your input parameters directly inside the Civil 3D Properties palette. 8. Troubleshooting Common Errors
Once your logic is complete, save the file. Subassembly Composer exports assets using the .pkt file extension. Open your Civil 3D workspace. Open your preferred (Ctrl + 3).

Subassembly Composer for Civil 3D is an essential skill for specialized design. By mastering points, links, shapes, and parameters, you can build versatile custom components that streamline your corridor modeling process and improve accuracy.
The tool operates on a logic-based flowchart system rather than traditional CAD drawing: Define Input Parameters
Autodesk University publishes class handouts that are often more practical than the official manual.
Use the "Target" tab in the Preview window to "pull" your surface target up and down to see if your logic breaks. API Expressions Once a closed loop is formed in your
The right side shows your subassembly, allowing you to simulate target scenarios.
Autodesk Civil 3D is a powerful software used for civil engineering design and construction. One of its key features is the Subassembly Composer, a tool that allows users to create custom subassemblies for use in corridor design. In this tutorial, we will guide you through the process of creating a simple subassembly using the Subassembly Composer.
At its core, it's a visual logic editor. You build a subassembly by dragging elements into a flowchart, connecting them, and defining their properties. The software then interprets this flow to generate geometry based on input parameters, making it possible to create anything from a simple lane section to complex, conditional structures like retaining walls or multi-layered pavements.
Build independent geometry sequences under each branch. The subassembly will dynamically choose the correct path depending on the engineering context. 6. Exporting and Importing into Civil 3D
To make a subassembly intelligent, you must integrate decisions and targets. This ensures the subassembly automatically adapts to environment changes, such as switching from a cut profile to a fill profile.
Create a new point (P2) relative to P1 using your Width parameter.
