I am using Enterprise/Dx Library and we are adding lots of 3d models to our existing Central library. but occasionally the 3D --> Models --> Update Library command fails to open the dialog box/window. Is there a fix for this? So far the only thing we have been able to do is begin a new PCB board, bring the parts in again and restart the process of pushing them over to the master library which makes it horribly inefficient when this happens. Any ideas would be appreciated.
