Another way, with Part workbench.

0. Add Cube
1. add Sphere
2. attach sphere to a vertex of cube you want to cut (attachment can be accessed by clicking '...' button next to MapMode property of Sphere, or from menu Part->Attachment)
3. Part Section between Cube and Sphere.
4. Attach a sketch to the three vertices of the section wire.
5. Draw something big enough in the sketch.
6. Part Extrude the sketch
7. Part Cut Cube with Extrude.

Thanks for this very good to get the equal distances from the vertex.

Race is on?
Here another way using PartWB.
- make a cube and chamfer it (selecting 3 edges at once)

To do it in PartDesign this way we need a DatumSphere :lol: .

You need a current 0.18 with OCC 7.3 or up. Select a face and call in Part WB: Menu->Part->Defeaturing

Hey, lazy means you can do something else with the time you saved! You don't need to admit that you'll be goofing off! ;)

Pity though that Defeaturing is not parametric.

I didn't think about that, but it's almost "natural" because it relies on a selection of faces.

To be sure, when working on imported solids, it does not make sense for the defeaturing tool to be parametric. Still, it could be useful sometimes. Kind of like Part Refine shape VS. OpenSCAD Refine shape feature, or the Refine property for PartDesign features and Part Booleans.
