I am using .NET to create an application to print assemblies and all associated SLDDRW files of all parts in the assemblies. I am using the swModExt.SaveAs("FILENAME.PDF", swSaveAsVersion_e.swSaveAsCurrentVersion, swSaveAsOptions_e.swSaveAsOptions_Silent, swExportPDFData, errors, warnings) function. Sometimes, but not always, not all the graphics print in the PDF. It is like the drawing does not fully load before the PDF function runs. But it is very random. Is there a known issue around this and what could possibly be a solution to this problem? Thanks
