dimensions
Are the dimensions needed to show to a client ??
Partworks or / Vectric could draw lines that would pass for dimensions with some text added.
Of course in a cad program, the dimensions usually attach to linework and update automatically when the linework changes. I worked with a guy once who thought the dimensions for a building had to be set to the nearest 1/256th.... a bit too precise for the framing crews.
The decimal point seems to be the most important on the z axis... x & y not so much....
