Bounding box of volume is larger after using Fillet function
I construct a geometric entity (e.g. a cylinder) and print its bounding box. Then I use the Fillet function on the edges of the cylinder and print its bounding box again and it is larger. Why is this the case? It is still a valid bounding box because it contains the volume, but I would expect the minimal bounding box. This behavior becomes problematic when the volume tag changes after using the Fillet function, which happens in some cases. In this case a want to get the new volume tag via the old bounding box (Volume In BoundinBox{...}), but there is no volume in the old bounding box. I hope that this issue became clear. I attached a geo file which reproduces the issue.bounding_box_after_fillet.geo
What is the best practice to handle this? In my opinion the bounding box should be the minimal bounding box and should definitely not grow after using the Fillet function.
