: A comprehensive, step-by-step guide from the Florida Department of Transportation. It covers the typical six-step workflow: creating projects, specifying parameters, adding geometry, modifying elements, previewing, and importing into Civil 3D. Subassembly Composer: Simple to Complex
Define specific attributes for selected elements and global subassembly parameters like Name and Side. 3. Typical Workflow: The Six-Step Process
: Focuses on troubleshooting and modifying existing subassemblies to meet specific design requirements. Access Class PDF .
Go to and save your work. Subassembly Composer compiles everything into a single .pkt (Packet) file. This file encapsulates all geometry, input parameters, logic trees, and help documentation.

Every custom subassembly relies on three primary components, known as : Points, Links, and Shapes.
If you are looking to find specific tutorials or comprehensive to take your skills to the next level, I can help you locate the best industry-standard resources. Would you prefer a guide focused on roadway design , water management , or general custom shape creation ?
Used to match alignments, feature lines, or polylines horizontally. : A comprehensive, step-by-step guide from the Florida
Apply a material code to the shape, such as "Pave1" or "Base" . This enables accurate material quantity takeoffs in your project. 4. Advanced Logic: Decisions and Targets
: Learning how to assign codes to points and links so they appear correctly as feature lines in your corridor. 💡 Quick Tips for New Users
: Creating "smart" subassemblies that adapt to targets (like existing ground surfaces) and user-defined input/output values. Go to and save your work
In the Preview panel, switch to . Drag the target sliders to see P2 dynamically move while the curb structure follows it seamlessly. Step 5: Complete the Structural Shapes
For example, you can use an auxiliary point to find where a 1:4 slope intersects an existing right-of-way line before committing to a structural subassembly shape. 6. Best Practices for Coding and Namespaces
