ghostscript pdf orientation

Guys,

I'm trying to create pdfs using ghostscript. In Proe I print the drawing to the generic postscript, print to file, set the page to A3, and set spin to

2. Then I save the file as *.ps.

I open GSview, and the drawing comes into view exactly as it is in Proe. The Media button has A3 ticked, and the orientation button has landscape ticked. Everything looks fine.

Then I try to save to pdf, using File/Convert/Pdfwrite.

I accept the default 600 resolution.

I accept the default Fixed Page Size

I create the file.

Then in Acrobat Reader, I open the file. It comes in fine, no error messages, A3 landscape page, but the drawing is rotated 90 degrees and truncates off the top of the page.

What am I doing wrong?

Thanks,

Dave
