7.6.2.11.6.7. Radius of chamfer/fillet larger than distance to adjoining geometry

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.

[Note]Note

This use case is very rare, so it should be no problem for regular parts.

Example:

  1. On the edge marked in red, a fillet is created by the Blend feature.

    PARTdesigner: Creation of fillet on marked edge

    PARTdesigner: Creation of fillet on marked edge

  2. Since the radius of the fillet is larger than the distance to the overlying geometry, the fillet hollows out this element.

    PARTdesigner: Result

    PARTdesigner: Result

[Note]Note

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

PARTdesigner: Extrusion extended downward

PARTdesigner: Extrusion extended downward

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.
