How to constrain an extruded part to a surface of another part?

I would like the helix part to be as long as the main body one. To this, I was trying to constrain the extruded circular surface of helix to the ring surface of main body, and possibly add an offset. I did not find the constrain tools in this view



What is the correct approach for such cross-parts constraints?

    Most possibly it is to create/edit the dependent part in context. You don't need to create the whole part that way, it might suffice to just create maybe two or three key mate connectors or start and end plane, then go into the part studio and create the part itself. You could also create both parts in one single part studio. I imagine, though, that the helix part could get a bit complex and have a dense population in the feature tree for itself, so one might want to keep it separate.

    If I understand this correctly - you have a multi-part, part studio, and want to move individual parts around. If this is the case, then I think you want to look at the transform tool. And I would recommend transforming by mate connectors.
    Hope this helps.
