Extrude, revolve, sweep, loft
The four core solid-creation operations turn 2D profiles into 3D geometry. Extrude pushes a profile along a straight path; revolve spins it around an axis; sweep drives it along a path curve; and loft blends between two or more profiles to create smooth transitions.
Each of these can add material or remove it, so the same operations that build a boss also cut a pocket.
- Extrude — the workhorse for prismatic features, with depth, direction, draft, and to-face options.
- Revolve — bottles, shafts, wheels, and any axisymmetric part.
- Sweep — pipes, gaskets, handles, and profiles that follow a path.
- Loft — transitions, blends, and organic shapes between profiles.
Fillet, chamfer, shell, draft
Modify operations refine a solid after its base features exist. Fillet rounds edges, chamfer bevels them, shell hollows a solid to a wall thickness, and draft angles faces for moldability.
These operations are edge- and face-aware and land in the timeline like everything else, so you can change a fillet radius or a wall thickness at any time.
Tip: Add fillets and chamfers late in the timeline. Cosmetic rounding early on can make later selections and booleans harder to reference reliably.
Boolean operations
Combine, cut, and intersect solids with boolean operations. Union merges bodies, subtract removes one body from another, and intersect keeps only the overlapping volume.
Booleans are the foundation of multi-body modeling — build features as separate bodies and combine them when you are ready.
Linear and circular patterns
Patterns replicate a feature or body across a grid or around an axis without redrawing it. Linear patterns space copies along one or two directions; circular patterns array copies around a center — ideal for bolt circles, cooling fins, and perforations.
Patterns stay parametric: change the count or spacing and every instance updates.
Direct push-pull editing
Not every change needs a new sketch. Push-pull lets you grab a face and move it directly to resize a feature, offset a wall, or extend a boss — with a live preview and on-screen readouts so you can confirm-then-commit.
It is the fast, tactile way to nudge geometry, and it records the edit in the timeline so the change is repeatable.
