What I have been attempting to do with little success is to create a Toolbar button to do the following:
Save the current drawing; then perform a Save As to the current drawing name +BAK.dwg.
The reason for this curious function is that despite the Recovery Manager, or perhaps because of it Civil 3D has the annoying habit of reporting that the recovery file is INVALID.
As a workaround to this annoyance I have adopted the habit of performing a save as to a DWGNAMEBAK.dwg, and then as save as back the original filename. In this manner I can depend on MY saved as file to be complete when C3D, and Recovery manager decides to munch my design file.
i would like to add this to a button to make it easier, and thus more likely to be used by other users; so that they too will stop losing work to this feature.
