I’m having problem printing out drawings to PDF files. Export to PDF works but PDF file takes forever to print because of issues with transparent surfaces (hangs at flattening surfaces).
Printing directly from layout prints out transparent surfaces as dotted (print preview also displays surfaces as dotted).
The only workaround I found so far is printing to Microsoft Print to PDF virtual printer. Then I can print it out from Adobe reader without issues with flattening.
