Projection

project() takes 3D geometry (faces, edges) and projects it onto your current sketch plane. This is useful for creating features that follow the shape of existing geometry.

Projecting a face​

import { sketch, extrude, project, offset } from 'fluidcad/core';
import { rect } from 'fluidcad/core';

sketch("xy", () => {
    rect(100, 60).center().radius(8)
})

const e = extrude(30)

sketch(e.endFaces(), () => {
    project(e.endFaces())
    offset(-5, true)
})

Projected and offset face

This projects the outline of the top face onto the sketch. Combined with offset(), it's a common way to create shell-like features or inset pockets that match an existing profile.

Projecting edges​

You can also project specific edges:

sketch(e.endFaces(), () => {
    project(e.endEdges())      // project just the edges
})

Multiple sources​

Pass multiple objects to project them all at once:

sketch("xy", () => {
    project(face1, face2, edge1)
})
