Points can be defined by Angle and Distance, Delta X and Delta Y, Slope and Delta X, or Intersections.

Set Start Point to P5 and End Point to P1 to close the geometry loop.

Once your logic tree tests successfully in the Preview Panel, it is time to export it. Step 1: Save the File civil 3d subassembly composer tutorial pdf

If your subassembly needs to find a Surface or an Alignment, define these here. 3. Building the Geometry (Points, Links, and Shapes)

If you have ever tried to create a complex road intersection, a retaining wall with a specific footing detail, or a dynamic drainage ditch in Autodesk Civil 3D, you have likely hit a wall. The out-of-the-box subassemblies are powerful, but they cannot cover every engineering scenario on Earth.

Drag a second below P1 . It defaults to P2 and automatically creates Link L1 . Change the Point Geometry Type to Slope and Delta X . Set From Point to P1 . Set Slope to GutterSlope . Set Delta X to GutterWidth . Add Codes: Point Code = "Gutter" ; Link Code = "Top" . Step 4: Create the Curb Face ( Drag a third Point below P2 . This creates P3 and Link L2 . Change Point Geometry Type to Delta X and Delta Y . Set From Point to P2 . Set Delta X to 0 (vertical line). Set Delta Y to CurbHeight . Add Codes: Point Code = "CurbTop" ; Link Code = "Top" . Step 5: Complete the Structural Loop ( Follow the same logic to close out the perimeter:

This PDF guide is designed to take you from "Zero to Hero" by breaking down the workflow into digestible steps. Here is what you will learn:

To make a subassembly search out an existing ground surface ( EGcap E cap G Navigate to the tab. Jacobson & Associates, Inc

: Strings assigned to points (e.g., "Top" , "Hinge" , "Subbase" ) used later for feature line generation in Civil 3D. Links are linear segments connecting two existing points.

Select the links that outline the shape (e.g., P1, P2, P3, P4). This allows for area calculation in Civil 3D. 4. Testing and Exporting (PKT Files)
