I am using Windchill PDMLink Release 11.0 and Datecode with CPS M030-CPS07
While check out the drawing from Windchill, Creo takes much time to load. it shows Not responding.
What version of Creo are you using?
Is it a single part or a complex assembly?
Are you checking out directly from Commonspace?
It may be that if your workspace is not empty, Windchill is running into issues with adding files to workspace. That can often make it hang.
