OCCT Fillets & Chamfers

Round and bevel edges with OCCT fillets and chamfers in Bitbybit. Almost nothing manufactured has a perfectly sharp edge, so this is usually the step that takes a blocky parametric model to something that looks and behaves like a real part. These pages cover filleting solids and 2D wire corners, chamfering circular and curved edges, applying a variable radius or distance along a single edge, and selecting exactly the edges you want by index. They also cover why a fillet fails when the radius is too large for the surrounding geometry, and how to recover.
