Periodically, when I FilletEdge, the inside corners won’t fillet. For example, see the following image: Does anyone know why this is?
I get the same, but only if the surfaces are split at the corner (for the screenshot I extracted that surface, but I ran the FilletEdge command while it was one single joined solid).
The split surface corner fails, but the other corner to the right is OK:
From your image it looks like this is also your case?
yes Rolf, this is exactly my problem
Try run MergeFace or MergeAllFaces on the object before running the FilletEdge, then you may have a better outcome with the FilletEdge command.
This obviously does only work with planar surfaces…
For other cases you will need to manually fix
fillededges trimming shortcomings.
True. Hence my wording “may”
