Hello,

I have a new question and i don't see it on the others post ...

In an assembly model, when i will place a part on an another part i need 3 restrictions of placement. These 3 restrictions make a placement game.

I have also the possibility to create some others placements games.

My Question :

Is it possible to to create many instance in a familly table with the placements games ??

Thanks and have a nice day

Olivier

Hi Oliver...

If I understand your question correctly, no, the family table is not the best way to achieve this. You can save sets of assembly constraints though and toggle which one is active at any given time. I don't know how to do this toggling via family table, however.

You can have different placement schemes, though. You can even save different interface definitions and recall them or leverage them for "automatic" assembly options.

If you have an example or can explain a bit further, we might be able to give a better answer.

Thank you!

Hi,

in assembly you can define several constraint sets for specific component (only one of them is enabled). Creo creates special parameter named PTC_CONSTRAINT_SET for this component. In assembly you can create family table and add this component parameter into it. Then you can set parameter value differently for different instances.

See

    That's definitely a right answer from Martin, this is an exact purpose PTC_CONSTRAINT_SET was introduced on the first place.

    Beyond family table, this parameter can be effectively used in Pro/PROGRAM getting fast variations of components positions, or - in case objects versioning poses a problem - can be guided via Flexible Components mechanism down the road. Note that proclaiming certain assembly branch as "flexible" you can add PTC_CONSTRAINT_SET for any level of downstream components, and any modification from here on will only be recorded at flexible sub-assembly level.
