Hello!

Hello!

I would like to solve a problem with you.

Often, after pressing the “make boolean operations to surgical guide base” button, an alert appears saying:

ERROR: Boolean operations to make fibula surgical guide failed.

Every time, I end up restarting the project from scratch until I can successfully generate the guide.

Can anyone help me understand at which step I might be making a mistake?

Thanks !!

BTW: clicking the “make boolean operations to surgical guide base” button many times should be as effective as restarting the project from scratch until you can successfully generate the guide. Please let me know if that does not work
