I am having trouble with the Rhino inbuilt save as PDF function in the print dialog (Latest Rhino 6 for Windows - 6.1.18037.13441). When using a large custom size page it fails to generate a PDF of the drawing.
Custom Page size for PDF print: 600mm x 2310mm
Note that a file is generated but no drawing data is contained. The PDF function seems to work fine when using the default set of page sizes.
