Question: What is standard scale in AutoCAD?

The standard scale will default to the scale list for a value. If an equal value is available in the scale list, it will be represented in the properties palette. Ex.) If a scale like 1/2″=1′-0″ is selected, its equivalent scale is 1:24, but 1:24 isn’t in the standard scale list, so 1/2″=1′-0″ is displayed.
