We recently upgraded from Civil 3D 2017 to 2019, and all of my users have been complaining about PDFs created in 2019 take forever to open and print.
I opened a file in 2017 and plotted to PDF, then opened the same drawing in 2019, plotted to PDF, and the opening time of the PDF increased drastically. In the 2019 created PDFs, upon opening, each individual object (lines, hatch, text, etc.) will display one-by-one, rather than just opening, like it did in 2017.
I know of the lag issues with transparency, but this problem hits all drawings. I received a 10 page plan set PDF a couple days ago that took 20 minutes to flatten before finally plotting.
I've tried using the DWG to PDF.pc3 file from the 2017 release and from 2019 and I get the same results.
Any thoughts?
