Unable to checkout Creo drawing
I have a Creo drawing in Windchill. It consists of three parts, a (.drw, .frm and .prt) files.
I have a change request that covers all three related objects.
When I try to check out any of the files I'm presented with a series of options on a pop up screen. I've tried what I think are the appropriate options but at no point does the file get checked out.
Is there a simple tutorial about that shows how to check out and edit a Creo drawing from Windchill.
My mech.eng. has moved on and I'm trying to cover some of his work while the search is on for his replacement.
Any help would be massively appreciated.
