I have 3 simple parts. I wish for the spring to have motion in my animation of this assembly.

YES- the spring has been created as a sweep and NOT a helix.

YES- the spring is undefined.

      Shouldn't the spring.sldprt basically flex and be manipulated in the part, like an accordian?

I have viewed several videos on how to do this and still confused.

What is an "in-context" relation?

Any help would be wonderful!

Enclosed are the 3 sldprt. to make up assembly desired.

Thanks
