I'm trying to create a nested set of copper tubings (3 small tubeswithin one larger tube) all following the same helical sweep. Ihave tried two different techniques for it:1) Create all tubeprofiles within one sketch. SW won't sweep the multiple sketches2)Create one helix for all 4 tube profiles and one sketch per tubeprofile. SW won't allow the same helix to be used in multiplesweeps (can't copy and paste and select)I have only been able to doit via one helix per tube. This is obviuosly workable but timeconsuming in that I have to create new helixes each time.We areusing 2007 sp4.Thanks for any help
