Drawings units changing on its own

[mwright1971]

I have a drawing from a client. When I first open the drawing, the units are set to inches (which is what I want it to be). But as I work on it, at some point the drawing automatically changes to millimeters. Has anyone run into this problem or have an idea or solution? It's really annoying, especially when I have to keep scaling blocks down that should be the correct size.

HI,

i thinks that it's changed because of installing or apploading lisp routine or plugins .

Check both MEASUREMENT and MEASUREINIT variable in the drawing.

MEASUREMENT set to 0 = Imperial (Drawing setting)

MEASUREINIT set to 0 = Imperial (System setting) (applied when opening file)

Both should have the same setting.

I tried the changing the variables, but it eventually went back to millimeters. Oh well, no big deal. It's a drawing from one of the clients we work with and they know just enough about AutoCAD to be dangerous and they are! Thanks for responses everyone!

Hi

I had the same problem exactly with an external file from a client. I just used a trick to bypass the issue:

- command DWGUNITS

- set the drawing unit to what you desire (in this case: inches)

- ok

- when the pop-up asks about scaling, just select "Don't rescale any existing objects"

- save a copy of the file

from now on, it will not switch units automatically. 

Hope it works for you too.
