METHODOLOGY OF THREE-DIMENSIONAL MODELING OF ROTATION SURFACES IN THE COMPASS 3D SYSTEM WHEN CONSTRUCTING A CROSSING LINE BY THE METHOD OF SPHERES
A drawing is the main design document that every engineer should develop and read. The discipline «Descriptive geometry» studies the theoretical foundations of building a drawing, the method of projection and is a discipline that is difficult for students of technical universities to perceive. To enhance visibility and eliminate psychological barriers to the perception of drawings of abstract objects studied in descriptive geometry, elements of three-dimensional modeling are introduced into the practical work on the construction of the line of intersection of surfaces of revolution by the method of spheres, which enhance the visibility of the process of solving the problem. A methodology for performing practical work with modeling elements is proposed. The classical step-by-step solution of the problem of determining the line of intersection of surfaces by the method of spheres is considered. The sequential construction of surfaces of revolution using the command apparatus of the Kompas 3d v 17 system is presente. The step of introducing the surfaces of the mediators of spheres has been analyzed and a model has been built to explain it. The analysis of actions for the introduction of elements of three-dimensional modeling when solving problems on the intersection of surfaces is given. The necessity of constructing a model with the participation of intermediary surfaces has been substantiated. The advantages of the given methodology are considered, consisting in the use of modern computer technologies in the process of teaching the classical graphic discipline, which enhance its visibility. Additional study of the command apparatus of a computer program, the creation of elements of motivation for the study of graphic discipline among modern students who possess computer technologies sufficiently and quickly perceive them.
