Hello I enjoy this site a lot and learning about XRefs. I am beginner in AutoCAD so i am not 100% sure if my cad setting dimensions and scale is correct, however it tells me that from downloaded files in lesson 4-7 - Xref files is a bed and it says the bed is wide 60cm. (??) I tried to use different scales: 1:1, 1:20, 1:50,1:100 and it says the same. I use metric system. Please what is the wide of the bed? So I know whats wrong and where should i edit my setting? Thank you Kindly H
