Rename your flowchart nodes from generic names like Point 3 to descriptive names like Point_CurbBack . This makes troubleshooting complex logic much easier.
Once you master the basics, the Subassembly Composer's power truly shines through advanced logic, moving from Beethoven's "Fur Elise" to his "9th Symphony".
Civil 3D cannot build surfaces, cross-sections, or render materials from your subassembly unless you assign standardized string .
This step-by-step exercise demonstrates how to build a standard parametric curb and gutter component.
Used to widen links along feature lines, polylines, or alignments. Elevation Targets: Used to match vertical profiles. Using the Decision Tool
Click inside the closed loop in the Preview window, or manually type L1, L2, L3, L4, L5 into the Shape properties box. 5. Advanced Logic: Targets and Decisions
Define input parameters (e.g., ShoulderWidth, ShoulderSlope). 2. Defining Points (The Geometry) Subassemblies are built using Points , Links , and Shapes . Drag a Point (P1) to the flowchart. Set it to Origin.
If you have ever felt constrained by the standard tool palettes in AutoCAD Civil 3D, you are not alone. While the out-of-the-box subassemblies (like LaneSuperelevationAOR or BasicSideSlopeDitch) are powerful, they often fail to meet the unique demands of real-world infrastructure projects.
Once opened, you will see:
Build components that dynamically adapt to target surfaces, specific offsets, or varying slopes.
