Using PDFCreator 2.1.1 on Windows 7/64-bit. In conjuction with Autodesk Revit 2014, PDFCreator is generating large PDFs from views with non-rectangular crop regions as described in the Revit support article here: http://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles/Large-PDF-files-when-printing-to-PDF-from-Revit-in-certain-views-sheets.html
Sample PDFs are available here, generated from both PDFCreator 2.1.1 and from Nitro PDF for comparison: https://drive.google.com/folderview?id=0BwbJl61_cgwcfmFRS0h5U0dRMF9RVnRUM2Q3TGdBVGY5b25NakJaUE5kM1ZPMUdnNzhHdVU&usp=sharing
The difference is dramatic: over a tenfold difference in generated PDF file size.
Autodesk's article claims that this can be resolved with the PDF generation rather than within Revit; the disparity between PDFCreator and Nitro seems to confirm that.
I did not find this issue in a forum search on terms "revit", "crop region", nor "large pdf files".
Is this something that can be fixed (or worked around) in PDFCreator? Is more information needed?
