Hi Sandeep,
I have tested the same scenario with WF 4.0 to Creo 3.0. Assembly having some 6000 to 8000 parts.
Due to version update, All the parts and assemblies should be saved in higher version first.
Then opening the main assembly will surely improve the performance.
in our case the assembly which was able to open in 3 to 4 minutes in WF4.0 took initially around 10 minutes to load in Creo 3.0.
then we tried to save all the backup with Creo 3.0. Then the loading time reduces to 50%.
Still due to system configuration which supports WF 4.0 (which uses less graphics) needs to be upgraded to higher configuration (Good graphics required for Creo 3.0).
Finally we reached nearly 2 minute load time for same assembly.
System configuration was the main parameter in our case.
This is something we have tested for implementing Creo 3.0.
So ultimately solution is as under:-
1) Save all older version files first in Creo 3.0 and then again try to open it in Creo 3.0. Surely will get result.
2) (If the above didn't work) try updating the system if you really have the old system. otherwise the first point will solve the issue as per my experience.
Regards,
Jimmy
