Trying to model a .206" O.D. spring using .026" wire .735" long free length.  I can get the main free section with no problems.

1.  I was able to add one full closed turn on one end with pitch = to wire diameter with no problem.  Second end fails to generate sweep, even though it seems to have been modeled like the first end.

2.  Decided to cut the first closed end with Through All Both Sides extruded cut.  Got zero thickness error.  I think I can fix this with a 3/4 turn instead of full turn and cutting down the pitch to less than wire diameter.  I suspect that a full turn with pitch = wire diameter takes out the wire cross section at the end of the turn. Got this part fixed, changed to less than one turn.

3.  Is there a way to merge three helical spirals into one so that I can do this in one sweep.
