The article is of an overview nature: more than a hundred sources are considered, each of which proves that descriptive geometry is present in all aspects of human life. The role of descriptive geometry is much broader than it can be imagined after reading textbooks. There is an opinion that descriptive geometry is a science, but few people know where it can be applied, and whether it is applied at all – after all, most university graduates can state with aplomb that they do not use descriptive geometry anywhere in their work. The conclusion is simple: they were taught very poorly. In this paper, it is proved that descriptive geometry is the basis for technical education and technical progress, it is proved by analyzing articles published in the journal "Geometry and Graphics" and other sources. And that it is simply vital to study descriptive geometry so that in the future our country will have the opportunity not only to create the latest technical equipment, but also simply have a technical future. The article consists of six sections, and in each section the fact of the presence of descriptive geometry in one or another direction of science and technology is revealed. The section on education proves that descriptive geometry is present in literally every textbook, and not only of a technical orientation: it is studied in art institutes. The last section shows the presence of descriptive geometry in the institutes of creative professions. The main conclusion is the following: "If someone picks up a pencil, a pen, a brush, a burning device, a cutter, a computer, a smartphone - this someone will undoubtedly be engaged in descriptive geometry, whether he is aware of it or not." Consequently, the study of descriptive geometry in universities is a necessary basis for higher education.
