I'm trying to do a Boolean Difference operation between 2 STL files I am importing. The operation doesn't complete properly, not subtracting all of the area. However, if I were to create an object in Blender itself then there is no issue subtracting away from the imported STL.
Is there a way to use one STL to subtract from another STL? or Is there a way to easily create a part in Blender from an STL (the geometry would be fairly complex in some instances)?
