Rounding & Blending
Chisel uses the same five-profile system everywhere fillets exist — primitive edge rounding, boolean blends, mirror seams, array seams, prism bevels, emboss inner corners. Pick the profile, set the radius, done.
What’s the difference?
Rounding is the radius applied to the edges of a single primitive. Set it on the primitive and every applicable edge softens.
Blending is the radius applied at the seam where two shapes meet — booleans, mirrors, arrays, emboss/engrave. Set it on the modifier and the join becomes a smooth fillet.
Both use the same five profiles and the same numeric range. The only difference is whether they live on the primitive or on the modifier.
