What problem does it solve?
Regions and 3D solids in AutoCAD/Civil 3D can be complex to create and modify; this skill consolidates operations for region creation, boolean operations, and solid workflows including extrusions, revolutions, sweeps, lofts, and Brep access into repeatable patterns.
Core Features & Use Cases
- Region creation from closed curves using Region.CreateFromCurves.
- Region Boolean Operations (BoolUnite, BoolSubtract, BoolIntersect) to combine or cut regions.
- Solid3d primitives and positioning using TransformBy (box, sphere, cylinder, cone, torus, wedge, pyramid).
- Solid creation workflows: Extrusion, Revolution, Sweep, Loft with cross-sections and paths.
- Brep API access for per-face/edge/vertex topology exploration and property queries.
- Mass properties access (volume, centroid, moments; and radii of gyration, principal directions).
- Coordinate system transforms and alignment with UCS or custom matrices.
Quick Start
Create a simple region from a closed boundary, extrude it into a Solid3d, and then apply a boolean subtraction with a second solid.
