Sweep

generators/sweep·v1.3.0

IN:2 OUT:1

SUMMARY

The Sweep turns curves into polygons, with many output options. You can create tubes, square profiles, or use custom cross-sections from a second input. The operator provides extensive control over orientation, twist, scaling, and color along the curve path. When Reorient Curve is enabled, Sweep uses the Orient Curve operator internally to properly align the curve's normal and tangent vectors along its path, ensuring smooth, evenly-distributed geometry without unwanted twisting or deformation in the resulting surface.

PARAMETERS
