I have had trouble exporting to PDFs in DraftSight (V1R4).  It crashes every time I use "PDF export", and I started having limited success bringing up the print dialog and creating a PDF from there, but it will still crash with certain sheets. I'm still trying to figure out what differentiates those sheets from others that work fine (same print style, same file).  I have experienced this problem on OS 10.7.5, and on a clean install on a brand new Macbook Pro running 10.9.

Any advice?  Other than this issue, I think DraftSight is excellent!
