Automatic generation of description geometry tasks using parametric templates

The range of disciplines in the graphic cycle includes descriptive geometry, engineering and computer graphics, basics of computer-aided design of objects and other training courses. The content of the listed disciplines involves the use of a large number of drawings, models, and graphic tasks. Some assignments are given to the student in the electronic form, in the form of drawings made in a graphics editor. Having an extensive database of electronic graphic tasks is an urgent necessity since each student in the academic stream receives an individual set of standard educational tasks. The formation of such sets of graphic tasks is a very labor-intensive part of a teacher's professional activity. As a solution, we propose to at least partially automate the procedure for preparing educational graphic tasks. The main idea is to fully or partially parameterize the geometry of the drawing, impose geometric and dimensional restrictions on graphic objects, create an external table of parameters and load these parameters into a graphic document to generate new versions of the drawing. The article considers an example of the joint use of the Compass graphic complex and Microsoft Excel. A number of examples demonstrate that the formation of a new set of graphic tasks can be reduced to several tens of minutes.
