Cadwork Math Utilities
Dependency-free geometry types for cadwork plugin authors. Frozen Point / Vec
pairs in 2D and 3D, a right-handed Frame3, Plane3, Line3, and projections.
Python 3.14, managed with UV. Millimetres are the implicit length unit.
Installation
uv add cwmath
From a checkout:
uv sync --group dev
Example
Copy this into a cadwork plugin (or cadwork IDLE). It converts a host
point_3d, builds a frame, drops a local point onto the XY plane, and
converts the foot back for cwapi3d.
import cadwork
from cwmath import (
Frame3,
Plane3,
Point3,
Vec3,
project_point_on_plane,
to_point_3d,
)
origin = Point3.from_xyz(cadwork.point_3d(1000.0, 2000.0, 0.0))
x_dir = Vec3.from_xyz(cadwork.point_3d(1.0, 0.0, 0.0))
y_dir = Vec3.from_xyz(cadwork.point_3d(0.0, 1.0, 0.0))
frame = Frame3.from_origin_xy(origin, x_dir, y_dir)
local = Point3(50.0, 25.0, 10.0)
world = frame.to_world(local)
plane = Plane3.from_point_normal(origin, frame.z_axis)
foot = project_point_on_plane(world, plane)
result = to_point_3d(foot)
to_point_3d imports cadwork only at the call site. Unit tests inject a
duck-typed factory instead of the host.
