Question

Speeding up family table verification

I am writing this whilst waiting for a family table to verify. We use FTs quite a lot but find that assembly ones can take a long time (~20 minutes) to verify, I'm interested to know if anyone has any tips to speed this up.

 

Typically our assembly FTs will have around 30-50 instances and include maybe 5 or 6 family tabled components or sub-assemblies. The overall assemblies aren't that big, typically around 25 components.

 

If anyone has any methods for speeding up FT verification, please let me know. Using Creo 2, M120

 

Thanks.
David

David,

Are you linked to Windchill? If so, backup the models locally and then verify the family table during an unlinked session. If you see an improvement you can then reach out to the Windchill community for their advice.

Yes, it does typically run faster outside of WC; we still have some model ranges that we have not brought into WC yet and they are faster to verify.

We have been able to make some improvements, for instance we have a mass parameter that is created by a relation from PRO_MP_MASS. This used to be an Initial relation so we had to verify the table twice for the instances' mass to update, but we moved it to Post-Regen so we now only have to verify once.

David Cox‌ Did moving the relations to Post-Regen improve the speed enough that that this is no longer an issue?

Were you able to get any performance suggestions from the Windchill Community?

The big benefit of moving the rels to post-regen was that we now only need to do the verification once (to allow weight parameters to update); it hasn't made the verification itself any faster.

We do know that working from our hard drives is faster than off Windchill. Our main Windchill server is located in the US - we are in the UK. We have a replica server on site here for the CAD data, and there has been some effort made lately to improve the performance of that server so I'm not sure there's a lot more we can gain there.

I haven't heard any other suggestions from the community, at this point I'm thinking there's not much more we can do to improve it.

Try talking to the Product Manager for Creo and ask for profiling tools to record memory and cpu usage for each feature as it is regenerated to see where the time is being spent. Perhaps if he hears it from one more person he will finally catch on.
