I'm working with a trial version. As I route pipe it is created as a Plant 3D object and has the appropriate content in the roll-over tips. When I close and reopen to continue with my design, the pipe and equipment revert to an AutoCAD object and loses the info in the roll-over tips. I no longer have Plant3D objects in my model. The very first pipe that I created remains a Plant 3D object. All other objects in the model lose that propery when I close and re-open. What am I doing wrong?
