Pretty dang good. Wish the user interface and graphics were modernized. Someone's bored nephew with a computer could really make the app 'pop'.

great, how hard would it be to add a 4 point saddle to the conduit bending section ? I realize 4 point saddle is 2 back to back offsets but I would like to see a diagram to punch my numbers in and how to make my bends
