We have GTCO Rollup 48x36 digitizers and under Win95 they're a big mess. I
also work for a contractor. All the drawings that I get from the Architect
(in house) are to scale.

What if I had the snap on?

Matt, I have digitized drawings a couple of times. ONLY when having
items at scale is not critical. Such as asbuilt overlay of a whole
complex with underground piping for our piping division (the originals
were hand drawn & spread out on four sheets). I tried this early on and
found that the shortcut in time was not worth the errors. I work for a
contractor & have to be correct.

I have a GTCO Super L II 48x36 digitizer. I have not been able to get it
running under 95, but have been under NT. When the digitizer driver is
loaded there are problems when running two or more sessions. One of the
sessions does not close completely and has to be shut down manually. I
had this digitizer running under R12 with no problems.

When needing to digitizer an existing paper drawing into a software program
here is what I recommend.

First, you will need a digitizer, Calcomp boards come in a number of size
ranges from 12x12" to 48X60" these tablets run with any software that is
Wintab compatible or can emulate 32 different tablets usually match a
driver that is supplied by the application.

Second, I would recommend considering AutoCAD LT 97 or 14 as your choice of
software. Both allow you to trace in a 1 to 1 ratio with the
Tablet/Calibrate command. This command allows you to pick a point off of
the digitizer and then tell it either by keyboard or picking the
coordinates off of the screen which point in Acad it should equal to. The
easiest way to get a one to one ratio with your digitizer is the following:
1.) open a new drawing and set the limits up for the same size of your
tablet
2.) use the zoom command to zoom to the extents (limits) or the drawing
3.) Type TABLET to get the option for CALibration (CAL)
4.) Pick the lower left hand corner of your tablet and enter the coords of
0,0 from the keyboard
5.) Pick the upper left hand corner of tablet for point to and enter the
coords to match the size of your tablet
ex: if you tablet is 48x36 then enter 48,36 as your coordinates
6.) Hit enter for the 3rd point
Now your tablet should be setup in a 1 to 1 ration with your graphic area
in ACAD.

I hope this helps answer your questions.
