Rounding
Chisel supports per-primitive edge rounding with five distinct profile types. Rounding is applied mathematically in the distance field, producing perfectly smooth results without extra geometry.
Available Profiles
- Round Profile (L2 norm): Perfect circular fillet (default)
- Sharp Profile (L4 supercircle): Tight-kneed supercircle fillet
- Soft Profile (L3 norm): Gentle C2-continuous blend
- Tight Profile (L8 norm): Squared fillet with tightest knees
- Chamfer Profile (L1 norm): Flat 45-degree bevel
How Rounding Works
Each primitive that supports rounding has these controls:
- Rounding: The radius of the edge fillet (0.0 = sharp, higher = rounder)
- Profile: The mathematical curve used for the fillet shape
For primitives with independent edge control (Prism, Trapezoid), Bevel and Cap Rounding replace the single Rounding slider, each with their own Profile selector.
