Have you ever worked on a complex drawing and made the fatal choice of running a command and selecting an object of considerable size? Like a 3D polyline with 30,000+ vertices?
Rather than having to CTRL ALT DEL and shut the entire program down with Windows Task Manager, it would be nice to have a command task manager where you can end a particular command that is attempting to process. I would guess this might be pretty difficult to do for Autodesk, but it would be great if there was a Task Manager for AutoCAD / Civil 3D.
There are times when working on complex drawings that you select the wrong type of object to work with and it freezes the software - eventually it will process but takes a considerable amount of time or doesn not process at all. Example is when attempting to trim a 3D polyline that came from the Minimum Distance Between Surfaces command but there are a number of others I've seen in the past.
I realize this could be something that would have to be built in from the AutoCAD side - not sure if it's even possible.
