Resource Hog (#136)
As mentioned over in the Support Forum, labelled "PDF Export Resource Hog?", SIM used approximately 1.508 GB of RAM to export a Class Diagram of 97 Classes to PDF.
Likely related, the program exported all 97 Classes to a single PDF page and I had to zoom in to 1200% before I could read the PDF.
I can forward both the PDF and SIM file to you if required.
