Doh'! Yes, I'm frustrated.
is that a question?
Um...no!
I went through this thread, fixed and tried many things and still my dimensions are reading 6" for a 12" object through a 1:2 viewport. I have been working here over a year, doing things the same way, and using the drop down list so my viewport SHOWS the object at 1:2 and paperspace dimensions on the same object READ 1:1. Now they are reading incorrectly for my purposes. I would very much like to fix this.
