So instead of actually adding an entire option for the a-b line to have straight edges, what about an option while mapping area/ ngz that while you’re driving the perimeter you could pause the mapping and it would self generate a straight line (much like when setting an area, it always has a straight line back to the origin location)
You could drive around areas/ obstacles and then when it’s a long run that you want a straight line, you just pause the mapping until you arrive at the next point, resume mapping, it will auto generate the straight line from the last point to your current point location?
