ADDED TABS ON UNFOLDED HELIX LOFTED BEND WILL NOT REFOLD.

SOLIDWORKS 2014  SP3.0  -  WINDOWS 8.0

I am making a sweeping curve for a conveyor and i need to add tabs for some crossmembers.  I created the two helix sketchs and then lofted the 3d sketch.  I then unfold and add my tabs but it will not refold.   error:  part contains features that cannot be unbent.  Please help.

thank you,

Rick
