I have been working with my Civil Engineering firm for just over a month now, and one of my co-workers had started talking about "checking data in and out of a drawing". I looked into it, and you can indeed take points, point groups, and surfaces. It is an interesting feature, allowing for multiple people to be working on one project without the hassle of all but one of the drawings being read-only.
Until we found out you can ONLY do this with point groups, points, and surfaces.
Is there a way to check other types of data (like objects, lines, or other bits of CAD data) out of a drawing and then be able to import it back into the drawing?
