Digitizer Calcomp
Digitizer Calcomp
(OP)
I have purchased a used CAD system, it has a old 386 computer, Autocad 12, plotter and a Calcomp Drawing Board III with a four button cursor. Plus I can use Autocad to make drawings
My question is how do you use it to digitize a large drawing 24" x 36" ?? I have purchased a used CAD system, it has a old 386 computer, Autocad 12, plotter and a Calcomp Drawing Board III with a four button cursor.
Every thing seems to work and I have the software and two instruction manuals from Calcomp. But what I'm looking for is a very simple step by step tutorial on digitizing a large or small drawing.
Thanks Bob

RE: Digitizer Calcomp
I did that once years ago using a calcomp and AutoCAD (I think R9). What I did was reconfigure the digitizer to use whole area for screen display, then set drawing on digitizer and draw lines as I picked ends of lines on drawing. Once area drawn that was on digitizer I moved drawing and reconfigured the origin of the digitizer and continued. Once done I rescaled the drawing to 1:1 based on measurement of the drawing. Very tedious. Might be easier just to get someone to scan drawing as a raster image and then overlay that and trace it. I'm not sure but I think that's possible with Acad 12. Been a while since I used Acad.

That's pretty much it. There should also be some means of setting the scaling of the tablet to match the drawing's.
