Applying a scale factor to text and dimensions was quite common
in the days before AutoDesk introduced paper space layouts and
viewports and everything was done in model space. For example,
let's say we were drawing a plan view of a house and ultimately
it would be plotted at a scale of 1/4"=1'-0". The scale factor
for our text and dimension heights would be 48 (1/4 * 12 or
4*12/1 = 48 ) So if we wanted our text to plot at a height of
1/8" it would have to be given a height of 6" in our drawing.
(.125 * 48 = 6 ). Is it possible you were thinking of viewport
scale factors? There is a way to assign a scale to a viewport
via the Zoom command utilizing the Scale option. It is referred
to as the n/XP scale factor. As an example to assign the scale
of 1/4"=1'-0" to a viewport the scale factor would be expressed
as 1/48xp. Another example: a scale of 1/8"=1'-0" assigned to a
viewport would be expressed as 1/96xp. While many older users
might remember and even use this method AutoCAD now makes it
easier to assign a s
