Hello all,
I am very new to using cad software. I am getting measurements on two .dwg files. The first file, I went to manage/units/unit system/ length type and changed this to architectural. I was able to get accurate measurements on the file once I did that. I opened the next .dwg and did the same thing. When I measure something that I assume would be about 100 feet, I get 0 1/2" measurement.

I have a feeling that this is a scaling issue, but I didn't have to scale the first file and it worked fine so I'm not sure what changed. If you need more info to help me out, I would be glad to provide that info for you. Thank you.
