Drafting standards in most parts of the world specify the a set of a relatively small fixed scales when printing CAD design. Scales such as 1:50, 1:100, 1:200, 1:500 and 1:1000 are usual. Here a designer uses a non standard scale of 1:800 and we how how to change the aspect ration of the drawing sheet and reset the scale to a more conventional 1:500.
We recommend including a scale bar (in model space) in all gCADPlus landscape drawings. These are available in the gCADPlus library > Details section.
