SolidWorks 2015 SP5.0
More than worthy graphics cards NVidia Quadro M4000.
Since we have gone to windows 10 we have noticed the material and appearances disappearing on drawings.
What happens is simple. We may be working on a drawing, perhaps navigate away from the SolidWorks drawing to a none related part, navigate back to the drawing and the appearance of the material, surface, or even cosmetic thread disappears. Our work around is to navigate to the model that depicts the appearance, then navigate back to the drawing and it appears (most of the time). We can't print and have the appearance show up without performing the work around.
For the routing program appearances, the colors of the wires disappear and only reappear when the drawing view is recreated. We can't print and have the appearance show up without performing this work around also.
I gather this is an issue with Windows 10 as we don't recall having this issue prior to our upgrade...
Has any one else had these issues?
