 Yes dxli, I am using the command line to draw with. The problem is not that the drawing is inaccurate, it's the diagonal dimension that I take off it without one of the snap options enabled. When I turn on the snap, it defaults (snaps) to either a horizontal dimension or vertical dimension.
How do I know it inaccurate? Because I have to rely on clicking on the corner by eye and each time I do it, I can get a slightly different figure.

Rallaz,
I'm using the diagonal dimension option "dimension -linear" as you suggest.

Lord of Bikes,
Ok, I will do a screen shot and post here.
I am unable to do one now - my file sharing site is not loading. However, it will just look like a simple rectangle with a horizontal dimension drawn in! The explanation above is what is required to understand what the problem is.
