...into a digitizer by attaching encoders to the x and y axes?
I regularly need to measure the areas of drawn shapes. If I could click a button when the crosshairs cover the appropriate corner points to capture the x-y coordinates into a .csv file, it would simplify my work.
Better yet, the inputs would take the place of my mouse, like a big digitizing tablet.
