When the “Bolt Factory” add-on is invoked to create a nut in Blender 2.75, the mesh lacks the open channel in the center.
Examining the source file (“Boltfactory.py”) reveals that there is a commented-out command line to accomplish that in at least the 2.73 and 2.74 versions:
self.bf_Minor_Dia = self.bf_Major_Dia - (1.082532 * self.bf_Pitch)
and it doesn’t appear even as a comment in 2.75.
Anyone have any more information about this?
