I'm having trouble with the new 3D thread tool. I've attached the drawing in question. I've created a part by 3D subtracting a number of spins from a main spin object. I now want to add an M5 x 0.8 female thread to the 4.2mm bore in one end. This bore was created by 3D subtracting a spin from another spin. I can't get the thread tool to lock on to the bore at this end - it will lock on to the bore at the other end strangely enough!
I've also tried new drawings with spins subtracted from spins, and then added a female thread to a bore, and they work fine. Any ideas why this one won't?
