Used to define the subassembly name, input/output parameters, target parameters, and superelevation settings. Subassembly Composer Autocad Civil 3d Tutorial Pdf
: Where you define the subassembly's name and create user-adjustable variables like width, depth, or slope. 2. Core Workflow Steps A typical project follows these six steps: Subassembly Composer Pt. 1 - Exploring the Interface
Autodesk AutoCAD Civil 3D is a powerful tool for civil engineering design, but its true power is unlocked when you move beyond standard components. The allows users to create complex, customized subassemblies—the cross-sectional building blocks of corridors—without needing advanced programming knowledge [1].
The logical workspace where you define the sequence of your subassembly. To follow along with this tutorial, you need:
: Apply "ETW" (Edge of Travel Way) to P2 to automatically create a clear feature line along the edge of the road.
Set the Slope to LaneSlope and the Delta X to LaneWidth . The preview panel will update to show a sloped line extending from the origin. Step 3: Extrude the Pavement Depth
Navigate to in SAC and save the project. This generates a unified .pkt file. Open your target drawing in AutoCAD Civil 3D. Open the Tool Palettes command ( CTRL + 3 ). If you share with third parties, their policies apply
A real-time graphic window showing what your subassembly looks like. It features two modes: Roadway Mode (shows how it behaves in a static state) and Layout Mode (shows how it behaves with active targets).
Target parameter is named in SAC but not assigned in Civil 3D target properties.
