is there no way to imbed sorta the original curve with the object - actually dont they all ready have the curve imbedded?
then i usually hide the object(ge lofted one) to do another version with the cross section/ curves
and its kinda annoying that the hidden object returns when I move a point

I can copy the curves again and thats what i do but seams and extra step

its not a major problem just quirky to me
