The attached is a spring part with 3 configurations, 3differentexpanded/contracted states.  Easy enough, right? ha! Ittakes, either SW or my machine, or I don't know what,about 15minutes, NO JOKE!, to either open the file for thefirst time, orchange configurations.  The part is prettystraight forward,Swept Helix/Spiral, end caps, etc...
Any help/suggestions    Attachments don't seemto beworking, click this for the file:Spring_6DIA  (3Mb)
