This graphic scale will update its length and annotations based on user input scale. Placed as a Symbol, this single family type can be used for any standard view scale.

After placing, the user simply updates the 'Scale Printed' and 'Scale Actual' instance parameters to set the desired scale. The Symbol will resize based on the input (2' long for even scales, 3' long for odd scales), and update the length designations below the scale bar.
