Do you know, that… ?

Rounding an operation has a lot of options, however, most are not widely known and used. The most common is the typical round rounding of walls, edges, etc..

If you are using this operation with the default settings and want to fillet edges near the holes – the fillet will be deformed. Of course, the degree of deformation depends on the geometry, i.e.. radius values, the size and location of the hole.

What then?

In that case, expand Fillet options and change the default settings Transition type on Keep surface.
