I am using TurboCAD 12.5 to design the framing of a room addition for my home. The problem is exchanging drawings with professional engineers. My drawings use only very basic design elements, so this is not about compatibility for fancy features.
The first engineer I worked with was using Autodesk Design Review 2010 to open my files. I exported .dwg and dwf files containing model space and one paper space and sent to him. He was able to open them and mark them up. However, when I got them back, I couldn't see his markups. Instead I saw this: The model space is now empty. There are 3 paper spaces, one of which is empty and two that shows the original drawing witout markups.
Now I am working with another engineer. She is using AutoCAD 2011, which is brand new to her. Again, she is able to view my files. We haven't yet had a chance to test whether her files, or my files marked up by her, will work in my program.
These may not be the last engineers I work with, so I'd like to have a broad understanding of what will work with what. Can anyone explain the problems I had reading my files after markup by Autocad Design Review 2010? What should be my expectation for 2-way exchange of files with AutoCAD 2011? Will I always have trouble when the other program is more recent than mine? What if anything would I gain by updating my software with respect to file compatibility specifically?
