This was the turning point. CADtools introduced a feature that allowed users to set a document scale (e.g., 1/4 inch = 1 foot). Suddenly, an architect could draw a 40-foot wall in Illustrator, and the plugin would automatically scale it down to fit on a printable sheet, while retaining the metadata that it was 40 feet long.

Creating and updating labels for lengths and angles is tedious without automation.
