FreeCAD: Explode part of an array directionally.

It not always going to be the case where mating parts have mating planar faces. They maybe any shape, circular with this pulley. But the Create Simple Group command from the Exploded Assembly WB requires a planar face to project from. So.., we create a simple piece of geometry, which has faces to project normal from. And can turned off when creating drawings or an animation, just don't delete it.
Multiple reference objects could be created which stay with a sub-assemble and exploded out multiple times.
In this assembly I created a separate part for the exploded bodies which where copied (not cloned) and the originals turned off.Show more

When using the Exploded Assembly WB: DO NOT deleted the ExploedAssembly folder or SimpleGroups when the assembly is exploded, the assembly or part will be left in the exploded position with no way home.
