Ilogic Iparts Slow

[Anonymous]

We have recently upgraded to Inventor 2018 and Windows 10. We have found that Ilogic rules that contain commands to change Iparts (iPart.FindRow ,ect) are taking significantly longer. A rule that used to take less than a second is now 20 seconds.

Can anyone shed any light please on what has happened?

Hello @Anonymous,

Try to add below code before iPart.FindRow() method.

ThisApplication.UserInterfaceManager.DoEvents() 

Please feel free to contact if there is any queries.

Thanks and regards,

No sorry this doesn't seem to work.

The problem seem to be the initial changing of the iPart. When the model assembly is first loaded and configured which contains the iPart then the iPart takes a long time to switch between state A and state B. However, if switching back and forth between the iPart states after the initial run then it seems to behave normally and take less than a second as it should.

Closing the model and re-opening then seems to start the process again and the initial ipart change takes forever.

The purpose of these models are for designers to run and configure the model once from a master file. When I have multiple iParts in the assembly the update is now taking about 4 minutes where it should be less than 1 minute.

@Anonymous,

Could you please provide sample assembly with iPart to test?

Please make sure that files are non confidential.
