I recently purchased several STL files so I can concentrate on carving Icons and crosses instead of custom signs. On a couple of the stl's there are blank spot's. how do I fill those blank spots in? This is probably very basic stuff to know so if there is a tips and tricks I should look for or a tutorial please point me in the right direction.
Thank you in advance and forgive me in advance if I don't respond right away. I have been fighting a nasty head cold which I cant seem to shake at all.
