I've not yet used 2006, but what I've been doing for years now is to put the
Drawing Scale info (metric/imperial and scale value) into Two (2) drawing
variables (which get saved in the Dwg file).

If I recall, there are three such varable names you can use (I only use 2 of
them). They are UserR1 to UserR5 and UserI1 (that is Eye 1) to UserI5. I
don't think that these are used much by anyone that I've ever come across.
Most don't even know that they are there (as they do not show up in SETVAR ?.

I use UserR1 for the scale factor (ie: 96 for 1/8th scale - 8 x 1/8")

And I use UserI1 for metric or imperial.

I retrieve them like the following:

(setq figscl (getvar "UserR1")) ; find Figure Scale factor

(setq Inmm (getvar "USerI1")) ; find if Inches 1 or MM 0
(if (= Inmm 0) (setq figscal (* figscl 25.4)))
(if (= Inmm 1) (setq figscal figscl))


If you are using In-House custom menus and Lisp routines, you might want some
one to check a few lines of their sourse code to see what's going on.
