In Graphic Geometry, Technical Drawing – Mechanical Engineering Drawing, establishing a measured axis projection of an object has many methods. Some methods of constructing axial projections measured from 2 projection planes are often taught: regular perpendicular, isometric perpendicular, evenly angled oblique, vertical weighing... [1,2,3,4]. Building the plane shuttering method for establishing the measuring axis projection of the object from 2 linear angles placed in two base planes. Through projections perpendicular to the base planes, learners have a general spatial view, easily visualizing 3-dimensional objects from the intersections of the two directions. Find the shape of a line and a face by finding the set of points in 2 perpendicular projection directions from which to calculate the true magnitude of that line and face. From synthetic lines and faces is projected the measured axis of the object by the plane shuttering method.
