how to make sweep parametric

[peysey]

Hi guys,

Please look at the screenshot.
I am trying to lock the sweep profile to the RP's in the family.
However, it gives errors all the way.. Like constrains are not satisfied etc...

Why I try this:
When it is not locked and when I flex, the sketch profile fall apart. The shape dies.
Therefore I try to lock ik to RP, so I can fix the shape of the profile and move it as a whole with the RP I locked at it.

How is this possible? I thought that this was a small request and should be easy to make?

Does anyone have done this before?

Thank you in advance.
