Boolean glitch on object - Creates duplicate rather than subtracts I have a cube (on the right side of image) I wanted to slice out an oval from. No matter how I try it will NOT subtract. It actually creates a duplicate object (that what I wanted sliced) and JOINS that duplicate to the object it should have been sliced from. Annoying! So I created the same objects all over again and it worked just fine as you can see with the rectangular object on the left. So NBD. I just want some resolution as to WHY it won't work on the first dang object. Try it yourself. Blend file attached. (disregard the image behind the cube on the right side)
If you switch to Union it will do the Difference and vice versa that's even though the normals look okay the object in fact is inverted on the Y axis look at the scale on the Y it reads -0.5 just change it to 0.5 and it will work as intended
