add and remove entities from contraints nx6.02MP2

[uwam2ie]

I'm a little confused. I have used the new bond constraint between two component. Now I WANT to add an other component to this constraint. In the editing mode I can select the new additional component, but Ok or Apply is greyed out. The same is on deselecting a entity from a constraint. Works as designed ? Any workaround? How to use this editing mode?
thx in ad

After double-clicking on the Bond Constraint in the Assembly Navigator, the Components currently included in this Constraint will be highlighted on the screen. Now select any additional components that you wish to add and then hit the 'Redefine Constraint' button, after which the OK/Apply buttons will become active.

The same procedure, only performing a shift-select (deselection) instead of a select, will work when removing Components from a Bond Constraint, except this only works if you're removing the 3rd or higher component from the Bond Constraint.

Note that you can NOT remove the 1st and/or 2nd component from a Bond Constraint, in an attempt to delete it, that you can only do by deleting the Constraint itself. However, you can remove one component and then immediately add another, as long as you remember to hit the 'Redefine Constraint' button once you've completed the selection/deselection step.

ok John works,
thank you,
I've tested and get a padlock on a corresponting constraint.
I removed the bond from the component, ok , but the padlock is still displayed. How can I resolve this ?

Have you created any Mirrored Components in this assembly using the...

Assemblies -> Components -> Mirror Components...

...function?

[uwam2ie]

no, but I found a solution,
I decativated and activated the constraint had a padlock.
I have created two arangements, an angle constraint arrangement specific, after that I changed some features in the components. ok some , some constraint I have to recreate, no problem, but not the arrangement spec. angle constraint.
Changing to the other arrangement some component spec. constraints especially the bond constraints results wrong.
Are there some information in how to use arrangements / and the bond constraint?
I'm looking to provide the example

 

[uwam2ie]

...example

 

[JohnRBaker]

There should be examples in the Documentation and there might also be material in CAST.

However, what you've done seems to be working OK, so what's the problem?

... Ok
switch from one arangement to the other an look at the model, a bond constraint no working correct.
thx in ad

It sounds like something is either arrangement specific by default when it shouldn't be or that the affected components already have some arrangement specific positioning that you have defined. If you're working with two arrangements then try going through the locking and unlocking procedure for each and then see whether the arrangements behave as expected.

Switching from one Arrangement to the other, I see NO problems with respect to any of the Bond constraints.

How is it that you feel that there IS a problem? How does it manifest itself? I see nothing, either in terms of feedback from the software or an unexpected result.

... I attached an avi:
the orange component in the avi is constrainted with bond option, why does it move switching the arrangement.
thx

 

[JohnRBaker]

OK, I see what you're saying. I looked at your assembly and while I have NO idea whatsoever how and why this is behaving as it is, I was able to 'fix' it. Just go to the Assembly Navigator, select the top-level assembly, press MB3 and select...

Arrangements -> Edit...

...and when the dialog opens, delete Arrangement 2. Now close and reopen the Edit Arrangement dialog and add a new arrangement. Now go back and redefine the arrangement specific values of the Angle Constraint for the two arrangements.

This should 'fix' the problem.

Anyway, give it a try and let me know how it worked out.

... redefine only a worse solution
this is only a simple example, working like the help, cast only arrangement spez. constraint have doubled frame like the attached pic. and in arrangement option to ignore all constraints has never been used. ~ constraints do not really work safe in arrangements
thx

 

[JohnRBaker]

But did you try what I suggested?

Did it resolve the problem?

Note that I've had NO problems assigning Arrangement specific Constraints, using either NX 5.0 or NX 6.0. Your example was the first time I had seen anything like that, but since there is no way of knowing exactly the steps taken during the creation of the Assembly and the applying of the Constraints, I have no way of knowing where this problem may have occurred or why. All I know is that if I start from scratch and recreate the arrangements and the arrangement specific constraints over again, it worked fine.

[uwam2ie]

recreation works,
As I wrote above, I had to redefine the bond constraint on the three component,the arrangements had allready existed.
After this the arrangement/bond constraint doesn't work anymore as expected.
Is there any history ( constrait/arrangement ) to think about in this case?
thx in ad

 

[JohnRBaker]

I still don't understand WHAT you're talking about! ALL I DID WAS DELETE THE SECOND ARRANGEMENT AND THEN CREATED A NEW ONE AND DID THE ARRANGEMENT SPECIFIC CONSTRAINT ASSIGNMENTS. I NEVER TOUCHED A SINGLE ONE OF THE EXISTING CONSTRAINTS IN TERMS OF REDEFINING THEM!

Attached is that assembly.
