Set it to Slope and Delta X with a fixed width as a fallback mechanism so the corridor does not crash if the surface target is temporarily lost. Step 5: Enclosing the Shape
To make the ditch daylight dynamically to an existing surface, we must introduce conditional logic. Drag a node into the flowchart below P3.
: Displays the visual output of your flowchart. Switch between Roadway Mode (shows how it behaves with templates) and Layout Mode (shows how it looks in Civil 3D tool palettes). civil design 3d subassembly composer tutorial pdf top
To start, launch the Subassembly Composer from the Autodesk Civil 3D menu. You can also access the software from the Windows Start menu.
Once you have your PDF tutorials ready, follow this foundational workflow to create your first custom subassembly. We'll build a basic lane and shoulder subassembly that responds to targeting inputs. Set it to Slope and Delta X with
: For points that need to follow complex surface constraints, using the "Slope and Delta X" geometry type allows you to compute the necessary elevation difference based on slope and projected horizontal distance.
Because this is a comprehensive, publication-ready guide, standard article formatting is used below to ensure deep, technical coverage of the topic. : Displays the visual output of your flowchart
Confirm all point, link, and shape codes are enclosed in straight quotation marks (e.g., "Top" , "Datum" ).

When looking for a downloadable PDF, your first stop should always be the source. Autodesk provides official documentation that is often printer-friendly or exportable to PDF.
Find and launch the Subassembly Composer from your Windows Start menu. It is a separate application from Civil 3D, though it is installed alongside it.
