If the radius of chamfer/fillet is larger than the distance to an adjoining geometry, material will be removed from the adjoining geometry. This behavior applies for chamfers and fillets in the same way.

|---|---|
Changing the length of extrusion does not affect the behavior, (since the Blend feature has priority and the material is removed anyhow).

The behavior of the CAD systems is different. Material will be added to the extrusion automatically and the shape of the blend will be adopted to the adjacent geometry.
