Is there any way to remove round corners created with LibFredo6 RoundCorner add-on after the drawing has been closed and then re-opened? Seems like I remember being able to see each corner in a list at one time, but I can’t remember for the life of me how I did it.
The *.skb backup file is one save behind the *.skp file.
That may help, depending upon whether the file was saved more than once after the round corners were created.
I use this plugin a lot when designing stuff for 3D printing. Just because of the non-reversal/non-parametric nature of SketchUp, I’ve usually keep a “squared” version of the model off to the side, and running roundcorner as a last step before exporting. The squared version lets me manipulate much easier if I need to make changes, and running the roundcorner plugin doesn’t take too long. Maybe that would be an option for you.
