I'm having the constant problem, with IV crashing when trying to export an UK/EU A0 sheet. If I drop down one sheet size to A1 the export to PDF works with out a problem.
I've got the latest SP and fixes installed, so I don't know if it is IV or Adobe XI Pro at fault. Plenty of memory, paging file set to min of 8192 Max of 32768 so there plenty of space, 8MB Ram. Windows 7
What I've tried is save the file as a different name, file is NOT compressed on the HD, the HD is not faulty I've ran several test & checks, the folder & file are not corrupted, no viruses reported after deep scan, so now I'm stuck here wondering why IV will not export an A0 sheet to PDF.
I just tried and have no problems exporting an A0 sheet using inventors export..pdf option.
Have you tried to just print it using the acrobat distiller printer thus avoiding Inventors export/pdf functions
I've tried from the FILE - PRINT AS - and then PDF it worked to a point but the reusing PDF image was very poor quality
Change the Quality in the setting for the Adobe Acrobat printer in it Properties, most likely it's set to Standard.
