I had Solidworks 2011 and Solidworks 2018 loaded on my computer for a while.
I just uninstalled Solidworks 2011 and now all the text on my drawings has turned
to Italic text.
Something is overriding the Document properties.
All dimensions, all the notes even the titlevblocks are all in Italic.
Changing the Font doesn't make any difference.
Changing the Drafting Standard Doesn't help either.
