Please send me the model where this happens if at all possible, We are trying to use a single default PDF exporter that we wrote for V6 which includes a lot of quality improvements over other PDF printers. I can’t fix this bug if I don’t have a sample to repeat the bug.
This is hidden by default. If you really need access to the Adobe PDF printers, go to the advanced section in options and change the setting for Rhino.Options.Appearance.ShowExternalPdfPrinters to True
