File > Restore Auto-Save CAD State

Restores the last automatically saved CAD State.

During model editing, every time you modify the geometry, the current CAD state is saved to a scratch file that is maintained between Map3D sessions.

This includes all information associated with your current session including: geometry, control parameters, material properties, construction lines, etc.

This allows you to return to exactly where you left off in a new Map3D session, or in the event of program crash.
