If this is just a simple in-exact operation that you want to do....just do it in Tinkercad. It is an online application offered free by Autocad. It is extremely good at editing uploaded stl files. Upload your stl file, then create a subtractive sphere. Position this sphere and then Group the two ite...

I believe, Andrea, that you are using a forked version of freecad - Linkstage3. This maybe be quite different from v.19xxxxx

You have errors in your pad. See the red exclamation points icons to the left of your pad in the drawing tree? Those shouldn’t be there. If you share the file, we can take look.also, v0.18 is now old, please try this on v0.19xxxxx available in the dev area.

Photo and fcad file would be a start so we can see what you are trying to do.

@chrisb, I’m using v.19 and have also noticed this same issue. I didn’t bother to bring it up because I thought it was my improper usage of FCad. Thank you for bringing it to everyone’s attention.

I just want to report back, and say that main problem seemed to be a BAD hard drive (conventional drive). I noticed that the win10 task manager reported very low data rates at full drive data capacity to the drive at all times (even when there seemed to be no need to access the drive). My computer w...

I replicated the error again and noticed an interesting error message: Illegal storage access! Please save your work under a new file name and restart application!

On the very bottom it says: Unhandled Base::Exception caught in GUIApplication::notify........
