I have checked normals and removed doubles but still cannot get the Difference operation on Boolean modifier to work properly. The choker object is hollow, however I expected the modifier would still function using these two meshes. My aim is to cut a hole at the end of the choker. I am able to use the modifier using other basic shapes in a new file. How can I correct this problem? The choker object is hollow to save on material costs when used for 3D printing.
You added the modifier to the
Choker as the target object.
Ultimately the some the
Cylinder part will get removed as the modifier is for the
Cylinder, not for the
Choker. But you want a hole in the
Choker.So the best solution is to add the
Boolean modifier to the
Difference as the operation, and the target object as the
Hope this helped!
