_SCALE_ will print 30 ft/.in.
_SCALESHORT_ will print 1:30 or 30:1
Can the format be changed to 1”=30’
Create a named expression called (for example) "PrintScaleFormatter" withthe following expression:
PrintDefinition.ScalePU & """=" & PrintDefinition.ScaleMU & "'"
Reference that expression in a pen table text substitution replacement string using:
<expr?name=PrintScaleFormatter>
