Abstract: A novel multifunctional contour scriber is disclosed for the use in scribing the intersection contour when an arbitrary geometric body intersects a pipe at arbitrary angle. This multifunctional contour scriber can also be used for scribing at any angle a circle, equally spaced points along a circle, an ellipsoid, a hyperbola, a parabola, an inner or outer cycloid, or an involute of a circle, etc. on a plane, a concave or convex surface. The invention consists of a magnetic base, a rotary unit, a hinge unit, a locking unit, a longitudinal rod, a longitudinal rod disc, a transverse rod, a transverse rod disc, guide sleeves, and scribing units. When scribing the intersection contour on the main pipe, the scriber is secured by the magnetic base on the main pipe.
