construction.loft
Loft between two 2D profiles into a solid SDF.

| loft | Loft between two polygon profiles with equal vertex counts. |
loft
construction.loft.loft(profile_a, profile_b, height, material=None)Loft between two polygon profiles with equal vertex counts.
Generates a :class:~cadjoint.sdf.primitives.loft.LoftedPolygon that shares both profiles’ vertex parameters and is placed on profile_a’s sketch plane. In the placed frame, profile A sits at -height/2 and profile B at +height/2 along the plane normal; vertex i of A connects to vertex i of B. profile_b’s own plane is ignored — only its 2D vertex coordinates are used.
Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| profile_a | PolygonProfile | Bottom profile; its plane places the solid. | required |
| profile_b | PolygonProfile | Top profile; must have the same vertex count as profile_a. |
required |
| height | float | Scalar | Total loft height along profile_a’s plane normal. |
required |
| material | Optional render material. | None |
Returns
| Name | Type | Description |
|---|---|---|
SDF solid sharing parameter references with both profiles, with its two planar ends bound on as solid.cap("-") (profile A) and solid.cap("+") (profile B). The ruled side walls are planar only by accident, so they are not declared. |
Raises
| Name | Type | Description |
|---|---|---|
| ValueError | If the two profiles have different vertex counts. |
Example
bottom = PolygonProfile([[-1, -1], [1, -1], [1, 1], [-1, 1]], name="a")
top = PolygonProfile([[-0.5, -0.5], [0.5, -0.5], [0.5, 0.5], [-0.5, 0.5]], name="b")
solid = loft(bottom, top, height=2.0)
