Constraints list

Constraints list

Constraints list

(OP)
I'm a new NX user and something seems very strange for me.
Why constraints in the list change places all the time? Is it possible to keep them in the same position. Usually, I would like to have the first constraints at the beginning of the list and the last consraints at the end of the list.

Hope that NX can manage this correctly.

Thanks in advance.
Regards,

Loris

RE: Constraints list

Hi Loris,
What NX version are you using? Could you please provide an image of what you are exactly looking for.

RE: Constraints list

Click on a part, open the dependencies window on the bottom of your Assembly Navigator. Then click the magnifying glass, there you have you're constraints concerning the selected part.

Best regards,

Michaël.

RE: Constraints list

(OP)
I'm using Nx7.5.

I had my assembly with the constraints list in a certain order. Then I closed my assembly. Then I have reopen it again, and the constraints list is different. The first constraint in my list is not the same as before.

I have the same issue with the parts in the assembly. The position of each part in the list is not fix. The parts are always in a different place in the list. From my point of view this is not acceptable.

Micky, I know this possibility but it's not what I want. smile i just want to have the constraints ALWAYS in the same position in the list. Same for the parts list.

I hope that with the picture, you will clearly understand what i mean... smile

Loris

Ps: I hope the pictures are attached. It's my first Post in this Forum... so sorry in advance if i made a mistake.

RE: Constraints list

Hi Loris,
Have you used any SORTING in the assembly navigator (based on component name\part name\description etc.)?

No special sorting has been done.

RE: Constraints list

The Constraint Navigator was introduced with NX 8.0.

That being said, I think you will find that one of the reasons that there does not appear to be a fixed 'order' to constraints is that unlike the old Mating Conditions (available prior to NX 7.5) Assembly Constraints are solved simultaneously, that is they are NOT solved in the order in which they were created, which is how Mating Conditions were solved. Therefore, no attempt is made to either 'sort' them or to even retain any specific order since it has no relevance.

Now it is true, that starting with NX 8.0, since Assembly Constraints can now be managed using their own 'navigator', you do have the option, like in the other navigators, to force a lexical sort of the listing by selecting the header of a navigator column. This will temporarily sort the list in either ascending or descending order by name or value of the columns field. But this will not be remembered nor will it change any constraint behavior, it merely changes to order of the list.

Thanks John for your answer!
And do you confirm... It is same "issue" for the part list navigator? It is not possible to have the same order in the part list in an assembly?

Thanks in advance!
Best regards,
Loris

RE: Constraints list

When you say "part list navigator" you're actually referring to the 'Assembly Nevigator', correct? If so, yes, the order of the parts as seen in the Assembly Navigator is arbitrary but they can be sorted by selecting whichever column header you would like to base a sorted list on. The same can be done, and more, with the actual 'Parts List' note on a Drawing. Just select the entire Part List note, press MB3 and select the 'Sort...' option and you will be given a dialog where you can indicate which column(s) of the Parts List do you wish to use for the 'sorting' operation. You can control whether you're sorting UP or DOWN and you can use more than one column to control the sorting by setting the order of the columns. For example, you could sort by 'Qty' and then by 'Material', etc.
