I am using the free version of Eagle to design a small dense board.
I am hand-routing the PCB, and using the DRC check frequently to check clearances.
I've twice accidentally hit the 'Auto'-route button in the last couple of hours.
The autorouter creates a mess, and so I waste time unpicking the tracks it makes.
I'd like to keep my workflow smooth and streamlined, so I'd prefer not to have to explicitly do a save every time I am about to click DRC.
How do I disable the autorouter? I'd like to disable the autorouter forever unless I explicitly enable it (e.g. a global preference), or disable for the project.
PS - Undo after autoroute would be a very useful feature.
