Do you mind elaborating on how you went about creating and
attempting to save the 3D PD F template? That may help explain why that you
are getting that message.
Choosing to save to an alternate location may help. You can
publish to 3D PDF templates you saved in a different folder as long as you tell
SolidWorks where to look. Go to
System Options > File Locations > Show Folders for> 3D PDF Themes
Then you can add a folder that you've saved 3D PDF templates to.
That's what it was. I tried the same thing on a different machine and had no problems. Now I need to figure out why my setting where off and walk around the department and figure out where everybody else is looking.
