Drawing in inches and millimetres

Hi,

I have been given a drawing which originally used inches as the primary insertion unit. As i live in europe i perfer to use millimetres. When i copy the drawing into a new file which has mm (millimetre) as the insertion unit the drawing appears extremely scaled down is this normal?

When using a template using inches as a primary insertion unit the drawing appears as if drawn at 1:1 scale as you would expect? Any ideas?

You could scale the original (inches) drawings to millimeters.

Then, you could work in mm's.

Scale the drawing x 25.4.

open a blank drawing.

go to tools>options>user preference> & under 'insertion scale', set 'source content unit' to 'inches' & 'target drawing unit' to 'milimeter'. Also make 'insunits' value '4'(mm) and

than bring in this exisitng drawing there using insert comand.
