I am using AutoCAD 2011, and no matter what orientation my layout is, when I Plot to PDF, the resulting file is portrait orientation. All landscape layouts have to rotated 90 degrees. I have Adobe Acrobat Pro 9.0 and cannot change this. Is there an fix either in AutoCAD or Adobe for this?
Another issue I have with this is that if I use a WIPEOUT in the drawing, some of them are blank rectangles after I rotate the drawing. Undoing the rotation restores the contents of the WIPEOUT area. I start out with a white background in the rectangle with a black line drawing, and end up with an empty black rectangle. These are overlaid on an aerial, but in that area, the aerial does not display, so apparently something is still lingering from the WIPEOUT.
