Instance Method Details

#apply_rotation(obj) ⇒ Object

This will be called on bent, so this library can work with rectangle pipes, if you overwrite this and let it rotate z by 90

#radians(a) ⇒ Object

Warning: sum_x and sum_y are both a quick hack at the moment They will ONLY work on bends if you do same thing in the other direction for example pipe.cw(20,30) pipe.ccw(20,30) This might be fixed in the future.
