Civil Design 3d Subassembly Composer Tutorial Pdf Top [new] -

Autodesk Subassembly Composer (SAC) is a specialized authoring tool for creating custom subassemblies in Civil 3D without manual programming

Open Subassembly Composer. In the tab, name your subassembly (e.g., CustomCurb ) and add a description. Step 2: Define Input Parameters

Always use industry-standard codes like "Top" , "Pave" , and "Datum" .

Define specific attributes for selected elements and global subassembly parameters like Name and Side. 3. Typical Workflow: The Six-Step Process civil design 3d subassembly composer tutorial pdf top

: A highly-rated tutorial that transitions from simple shapes to complex subassemblies with targets. View Class Handout .

Instead of sequential geometry creation, use Decision nodes that fire based on "Event Triggers" (e.g., reaching a maximum slope length). This prevents the corridor from crashing in steep terrain.

Click Create Parameter . Name it LaneWidth , Type: Double , Default Value: 3.60 (meters or feet). Define specific attributes for selected elements and global

In the Slope field, enter your input parameter for the slope (e.g., -0.333 for a 3:1 downward slope) or reference a custom Input Parameter named InnerSlope .
