Aligning to cylindrical parts
Aligning to cylindrical parts
(OP)
I'm working on a design concept that involves running a length through a metal cover, then bending it upwards 90 degrees and running it parallel to the cover. To help control vibration, I wanted to add a pin that will weld to the cover piece and the pipe. However, I cannot figure out how to align the pin to the center of the pipe. I have a "Touch" constraint to make sure the pin contacts the cover plate, but I don't know to make sure that the pin is centered on the yellow pipe shown in the picture. I've tried all the constraints and none of them seem to do the trick. I'd prefer not to do a "Distance" constraint, since the location of the pipe may move.
Unfortunately, the full model of the cover is marked as a secure component and I cannot upload the model. Any help would be greatly appreciated.

Anyway, thank you for your help, it is very much appreciated.

The datums may not show, but the constraints will still be utilizing them.

You can simply change to the "entire part" reference set to reference the datums, but the display may be overly cluttered with other part geometry. I like the dedicated reference set because it makes the constraint geometry more obvious to others who need to work on the file and/or assembly (and a good reminder to myself a few weeks down the road!).

The logic of not having a constraint that is made for centering cylindrical objects escapes me but I am no fan of the new constraints system. I started using it as soon as I got NX5 in the hopes of learning what it does better that Mate but no joy.
This is currently my biggest beef with NX. The assembly system is not logical, clear, or user friendly. Which is a HUGE departure from the rest of the package. The only saving grace for me is that my assemblies are simple, if I made copiers or something I would be foaming.
