extrude
construction.extrude.extrude(
profile,
depth,
material=None,
draft=0.0,
twist=0.0,
)Extrude a 2D profile into a solid.
Generates an :class:~cadjoint.sdf.primitives.polygon.ExtrudedPolygon that shares the profile’s vertex parameters and is placed on the profile’s sketch plane. The solid spans ±depth/2 around the plane.
Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| profile | PolygonProfile | PolygonProfile to extrude. | required |
| depth | float | Scalar | Total extrusion depth. | required |
| material | Optional render material. | None |
|
| draft | float | Scalar | Draft angle in degrees. Positive values taper the walls inward as local z increases; the profile is exact at the bottom cap. | 0.0 |
| twist | float | Scalar | Total twist in degrees over the full depth. Non-zero twist makes the field non-1-Lipschitz. | 0.0 |
Returns
| Name | Type | Description |
|---|---|---|
SDF solid sharing parameter references with the construction tree, with its analytic faces bound on: solid.cap("+") and solid.cap("-") for the two ends, solid.side(i) for the wall swept by profile edge i, and solid.faces for all of them. A drafted or twisted extrusion declares none — see :func:cadjoint.construction.faces.extrusion_faces. |
Example
profile = PolygonProfile([[0, 0], [2, 0], [2, 1], [0, 1]])
solid = extrude(profile, depth=0.5)
boss = PolygonProfile(SQUARE, plane=SketchPlane.on(solid.cap("+")))
