I'm a new user and i'm trying to use a CalComp digitizer with DraftSight.  It works in the drawing screen but i can't get it to draw a line accurately.  I'm tracing paper patterns that i want to then modify with the cad software.

When i draw a 3 inch line, it shows the X line as 2.2828 which gives me a scale factor of 1.31417.  I cannot find anywhere to set the global scale factor so that all lines would be drawn to actual size.

I've modified the OPTIONS -> Drawing Settings -> Behavior -> Line Style Parameters and tried the "Global Line Scale" , which didn't work, then i tried the "Line Scale for New Entities".  Nothing worked.

I also tried the OPTIONS -> Drafting Styles -> Dimension -> Linear Dimension -> Scale Factor but that did not work either.

I've searched all over the internet and through the help files.  I find lots of scale factor options, but nothing that will give me what i need.

Is this not possible in DraftSight ?
