Saving Illustration while in Perspective mode Question

Hi Everyone,

Does anyone else have issues saving an illustration while in perspective mode? While in Orthographic view, saving the illustration takes a couple of minutes. I am saving the same illustration in perspective mode and it has been 26 hours and it is still rendering. The file size is only 56 MB, but is taking up to 10 GB of ram on my computer. Do you have any suggestions? Can you save figures in perspective mode as a line drawing?

Sincerely,

Dustine
