Parametric primitives
The five built-in shapes and the size and segment parameters that reshape them — before you start poly modeling.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
Every scene starts from five primitives. Each is parametric: it has size and resolution sliders in the Properties panel's Geometry section, and you can switch a primitive's type from the Primitive dropdown.
| Primitive | Parameters |
|---|---|
| Sphere | Radius · Width Segments · Height Segments |
| Box | Width · Height · Depth, plus W/H/D Segments for surface detail |
| Plane | Width · Height, plus W/H Segments |
| Cylinder | Radius · Height · Height Segments |
| Torus | Radius · Tube · Radial Segments · Tubular Segments |
Segments = smoothness and detail
Segment counts control how finely a shape is divided. More segments make a sphere rounder and give a surface enough geometry to show a displacement map's bumps. They also cost more to render, so dial them up only where you need them. There's a one-click Subdivide for displacement button that raises the count automatically when a material needs it.
