Rounding & Blending
Chisel rounds edges in three places, all with the same five profiles:
- Rounding rounds the edges of a single shape and is set on the shape.
- Blending rounds the seam where two things meet and is set on the modifier.
- The Smooth modifier sets a minimum radius for every edge and seam of a shape.
These roundings are part of the shape itself, not added geometry, and they update as you move or change the shapes.
