Hello Michael,

So ACIS fillet seems to have some sort of 'auto add tangent edges' feature, but ... no all the time.
In this example I'm trying to fillet this cube, and depending what edge I select, the result is a little bit unpredictable. The red dot represents what initial edge I can click to fillet the whole loop at once. In the fist one, any of the 3 edges is fine: The second version, only one of the straight edges will process the loop at once. Last 2 models, there is no auto-loop at all.

I'm starting to really like this auto add tangent feature, but off course use should also have the choice ... is it something you planning to add at some point ?
