Mathematical support of the drawing when designing parts in mechanical engineering

The work uses a scalar-parametric form of description of orthogonal projections of geometric shapes. The mathematical apparatus is based on the methods of analytical geometry, which are made in accordance with traditional graphic algorithms for both the representations of geometric objects of various classes and the solution of positional and metric problems.
It is recommended for students, graduate students, teachers of technical universities, researchers and design engineers working in the field of engineering graphics cybernetization when developing graphic packages on different programming languages, as well as in solving the problems of CAD - visualization of geometric objects and processing parts for metal -cutting CNC equipment
