This is where I see the main problem. The drawing scale has to be decided before
the drawing is started. The drawing scale is then almost cast in stone and cannot be changed anymore without a significant effort. Line widths and dimension sizes are not the only things that are affected by the drawing scale.
The drawing scale determines the way how things are arranged in a drawing, the distance between text labels and your drawing, the size of text labels, the border, the scale of hatch patterns, etc. Unlike other documents, drawings have a fixed scale and that scale should be decided as part of the planning, before the drawing is started.
If you do need to print a drawing at different scales, you would have to create one separate drawing for each scale.
