Arrgh. I am also having major problems with the fillet tool after upgrading to 12.5, worked fine in 11.5 but things that I had done over and over in 11.5 produce strange results very frustrating!
The fillet and trim does not work properly I have to use just fillet and manually trim. Trying to fillet between a line and arc is ridiculous.
Why was this messed with???
When is this going to be fixed?
