Primitive Shapes
The 'primitives' are accessed through the modeling API using the following:
const { cube, ellipse, star } = require('@jscad/modeling').primitives
2D Primitives
| Primitive | Notes |
|---|---|
| const mypath = arc({center: [2, 2], radius: 2, startAngle: Math.PI, endAngle: Math.PI * 2, segments: 64}) | API |
