Re: #4828 PartDesign: inverse for pocket
it's definitively more than one single extrusion and cut, and it's also problematic (not to say impossible) to obtain the addsubshape from a common operation. If we don't need to go with the more expensive operation we should not use it. In simple projects you will not feel the difference, but on complex model (specially on low end computers) it can be noticeable.
Re: #4828 PartDesign: inverse for pocket
That has to be compared with a single cut (plus adding a wire which is a very fast operation).
And I would also add a refine to get rid of the additional edges in the split plane (not created by the single cut).
Re: #4828 PartDesign: inverse for pocket
A refine can break a model. It should never be applied automatically unless configured as such in the preferences.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.
Re: #4828 PartDesign: inverse for pocket
In fact. And this is another argument against "split+common+union" which would require also a refine to get the same result of "pocket with sketch+wire"
