I'm trying to create stl. files for rapid prototyping , and get the warning that the part is in negative space. How do I alter that? I've moved it so all the integers describing maximum and minimum of the xyz axes are positive in the stl. menu , but still get the warning.
Also , regarding the other factors in the stl.menu , is there somewhere that tells me what different values of Angle and Distance might mean in practice?
Thanks for any assistance.
