Why are some pages rotating in book pdf: followup

[Fred Staal]

Here is a followup: The FM pages with pdf graphics (from SolidWorks)
will remain in correct portrait orientation after printing to .ps and
distilled to pdf IF they are rotated ccw 89.999 degrees; however, if
they are rotated 90 degrees they will cause the page to rotate cw to
landscape orientation in the pdf output. It would seem that a rotation
setting to 90 degrees is being confused with some page orientation
setting. Its still difficult to know where this is occuring; I'm wary of
the SolidWorks pdf conversion (is their driver really ps or an
emulator?) but it seems like Acrobat or Framemaker is confused by some
rotation setting as well. ???
