Is editing logic the best way to limit selections to only holes?

EvanReese

Is there a selection filter that would limit user inputs to only cylindrical holes, or do I need to manually remove bad selections with editing logic?

lana

There is no such filter.  GeometryType.CYLINDER && BodyType.SOLID  is the closest thing. You can use editing logic so that selection window would not have extra faces  or you can filter out wrong cylinders inside features, highlight them and put up an info message. I'd prefer the latter to just quietly dropping selections.

Thanks, @lana I was planning to drop them and add a message, but I like your philosophy more. It's even clearer.

Would be nice to have a filter for inner/outer rotational faces based on the test whether face normal line intersects rotational surface axis in positive direction

How would you want a toroidal face to behave with respect to such a filter?

@ilya_baran for this I think the filter need to have a third case for faces that have both external and internal normal. If its not computationally expensive
