Assembly Constraints (Center) NX 7.5

[Cid1979]

Trying to use Assembly constraints (Center) command and it lets me pick the first face of the part I want to constrain but when I go pick the second face it picks the whole body, When using mating conditions back in previous versions using center mating conditon you pick the face of the first part and a face for the second part, but using assembly constraint it's not working the same.

I assume you are talking about cylindrical parts. Use align and select infer center axis.

10-4 Thanks for the help, then what's the point of having the other Center command.

 

[stThree]

I use center for rectangular shapes (center 2 to 2) or round parts in slots (center 1 to 2 or 2 to 1 and infer center axis). Or centerting a c-channel to a plane or something like that.

So you guys think that assembly constraints are better than mating conditions from previous versions?

 

[ewh]

yeah!

I am not a noob to NX started of UG18 but could you give a brief description as to why you think Assembly constraints are better than the old mating conditions from previous versions?? I am just trying to see the advantages to them and as why they went that way versus just making mating conditions better.

 

[ewh]

I find them easier and more consistant to work with the legacy mating conditions.
Resistance is futile.

When creating Mating Conditions, have you ever gotten an error message saying that you had a 'Circular Reference'? How about wishing that you could change the fact that the first Component placed was always the FIXED one? Or have you ever wished that you could have TWO components set as FIXED? And when you discover how often 'Concentric' can be used and how easy it makes placing such things as shafts, pins, bolts, etc, you'll wonder how you ever lived without it.
