Topic: Howconvert a metric drawing to inches.

To go from metric (mm) to imperial (inches) wouldn't you scale by the inverse of 25.4, or 0.03937007874015748?

*facepalm*

Yes.  I was all flip flopped on my direction of scaling, there.

Or as I do it, scale by 10/254

Slick!
Got to try to remember that one if and when I ever get a metric drawing.

Yea, I only learned that a few months ago   I was always whipping out the calculator and dividing 1/25.4 (since you can't do a decimal in a fraction in Autocad) and an engineer saw me doing that one day and gave me that tip.  Brilliant!  That works in a -lot- of situations, actually, I've found.

I've been working like that for many years, especially when trying to work out viewport scales when we're doing civils drawings as they work in meters

Ive had a few before and just changed the INSUNITS (UNITS) var to Inches (if working on a metric drg or vice versa) thus leaving the original drawing intact.......

I find it easier to copy all w/ a base point and paste it in a new inches drawing at 0,0,0, then scale all. If you dont you should change the measurement, insunits and the other 2 insunit setvars to reflect inches, otherwise inserted blocks go crazy and hatch is wrong. Also you need the new dim styles

be much better to convert all the inches dwgs to metric!

Not helpful, I know.  Sorry
