Good morning. I'm quite new to Civil 3D and currently I'm working in a company that uses several computers, some with recent versions of AutoCAD Civil 3D (2015) and others with a 2012 license. I was adding and editing some COGO points in 2012 just fine and then I sent it to my boss that edited it in 2015. As a result, it is now impossible to do anything associated with the toolspace in the drawing. In fact, the toolspace is not even displayed since it was edited in a "recent version of the software". Is there anything that can be done about it? I have to use my home computer to make all the work (since I've a 2015 student license), but that's unsustainable.
Glad for all the help yet to come
