Free assembly constraints in subasembly in nx7
Free assembly constraints in subasembly in nx7
(OP)
Please look at the attached picture. Blue line shows assembled rod (its a subassembly). I left one free constraint for the one end of the rod (it can slide along red arrow, and I can slide it manualy then I am editing the rod). Then I put this subassembly to an assembly, I want to connect both end of the rod to the corresponding holes. Of course, I want to slide free end of the rod in order to make both ends concentric. But after adding the last constraint (red circle) as touch/align ->infer center/axis, I am getting an error, and constraints cannot be applied. How to make my rod work as I described?
P.S. I am using new assembly constraints.
thanks

Or, make use of Family tables.

As for your second question, this approach will solve that as well since these 'overridden positions' are unique to each assembly that you use this sub-assembly in. That is, the same sub-assembly can have different positions in different assemblies. In fact, if you loaded two or more copies of a sub-assembly into the same main assembly, using this approach you could position each individual sub-assembly differently, yet still only have to create a single sub-assembly with one set of parts and constraints.
Anyway, give it shot and let us know how it worked.

Yes, I remember using override position in NX4 (its quite handy method),but here, in NX7 I was not able find this :) even after you describe how to find it. If I press MB3 on the rod - nothing happens. After pressing MB2 on the rod I get standart context meniu (see attached), and as I have read documentation, I thought that override position was designed only for mating conditions, but not for assembly constraints.
Am I wrong? :/
