Ah, that helps a lot.

IMHO, the conversion of AutoCAD data (vectors) to a TIFF file (raster) is
not a good approach. Vector data is very compact and scales to any viewing
magnification. Raster data is a fixed resolution, and does not scale at
all. They tend to be large files and load very slowly. What you really
want is to convert from AutoCAD DWG format to another vector format. My
suggestion would be to convert from DWG to PDF. PDF can hold both raster
and vector data, since it is based on postscript. PDF is a dream come true
for CAD, as it provide an excellent way to archive drawing data. Nearly all
CAD systems can export PDF. Depending on the version of AutoCAD you have,
you might need to plot to a postscript driver and set it to save to a file
in the PDF format. Bluebeam software makes an excellent PDF converter
specific to AutoCAD. I usually setup a batch conversion and let it run
unattended.

This doesn't solve the problem you asked about (viewing multipage TIFFs),
but might make life easier down the road.

Tried KFaxView, no joy... Have to keep going....

OK, well I see that I opened a can... The drawings are done I believe in
Autocad. On the company M$ box I use either the M$ viewer which does
or does not see the pages... Or I use the company "official" viewer
something called Fastlook Plus by Kamel Software in Winter Park, FL

They start out as .dwg files and after the run them through something
does the conversion, they end up with the tiff files. I was asked if Gimp
would open them, indeed it does, but takes forever, and there are times
that I just need to pop open a file look at it and close it up, with the
speed
that Gimp opens them I would be way behind on work on those days
when I have to open machine drawings several times a day.

I will try to find out what they do the conversion with, I just realized
that
the person who knows how is very interested in Linux, indeed I work on
several projects with him and he has seen my linux machines and at the
same time suffered multiple sessions of grief with Bill's product and I
am sure would be happy to tell me what the conversion tool is.
