The 'expansions' are accessed through the modeling API using the following:
const { expand, offset } = require('@jscad/modeling').expansions
| Expansion | Notes |
| const newshape = expand({delta: 2, corners: 'round', segments: 64}, oldshape) | API |
| const newshape = offset({delta: -4, corners: 'round', segments: 64}, oldshape) | API |
