Modeling Boolean Modifier Difference Not Working Blender Stack Exchange The carve library that blender now uses internally for boolean operations has problems with manifold geometry. just select nothing in edit mode and then hit shift ctrl alt m (select non manifold, won't work with face selection) and see what is getting selected. there are all your problems ; ). The geometry of your 2 objects is not ideal. i’ve redone them quickly to give you an idea: boolean picto.blend (934.2 kb).
Modeling Boolean Modifier Difference Not Working Blender Stack Exchange Try putting the boolean modifier at the bottom of the stack, after the solidify and subdivision. note that a union boolean rather than a difference boolean is probably what you want. a difference boolean will subtract the "handle" cylinder from the bowl of the spoon, leaving behind a hole. The native boolean modifier does a lot of mistakes and makes bad topology really often. i suggest you to get the "booltool" addon (user preferences > add ons > booltool) and try with it by the menu object > booltool operator. When i use the difference boolean modifier, the hair disappears instead of deleting the overlapping hair with the mesh. i’ve tried removing doubles and recalculating normals (outside and inside) but it still doesn’t work. please help! and you have internal faces too :. Booleans in blender not working? you're not alone, here’s why it's breaking and two simple fixes to save your model.check out the learning hub at renderhub f.

Adding a solidify modifier at the top of the stack and un checking "only rim" appears to cause the boolean operation to behave as normal. this could be a temporary workaround, but reveals that the boolean difference operation cannot presently work on objects without thickness (ie. a 2d plane). added subscriber: @stan pancakes. Most of the common problems people experience with the boolean modifier are generally down to only 2 or 3 things: normals, doubles (or overlapping geometry), non manifold geometry. # normals. faces have a direction, it may seem like a weird idea but it's necessary in computer graphics to give a polygon (different word for face) a direction. If you do them one at a time, can you get any of them to boolean correctly, or do they all fail? something else, verify that all your meshes are enclosed, have no overlapping faces and have their normals pointing the correct direction. If you want to approach it this way, you need to make bools active but not applied and apply all modifiers at the end of your modeling, the other way would be to cut it, disable your modifiers and retopo your model to fit that bool so that rest of your modifiers works as intended.
