Distance Command not Working

[Anonymous]

Hi, 

I'm using AutoCad on a Mac and I have a problem that just appeared and wasn't here before. When I use the dimensions command to display the dimensions of something , the dimension does not appear, only something else appear (on the picture). I don't understand why it is doing this, I tried changing almost every settings but nothing has changed. Thanks

Welcome to Autodesk Forums!

It is dimension, but in wrong scale. You see huge arrows (a part of them).
If you are using associative dimension style, than you need to check the scale on the Status Bar and change it.
If you are using non associative dim style, you need to change overall scale factor in Fit tab of "Edit dim style" window - go to menu Format -> Dimension Style -> select Modify from "gear" menu -> Fit tab -> change "Use overall scale" value.
