At the beginning of this paper a short review of known geometric and graphic tests has been presented, and a practical lack of test tasks on computer graphics tools application for geometrical simulation problems solution has been emphasized. The test tasks directed to assessment the level of intellectual abilities related to the optimum choice of solid-state simulation tools for creation and editing products’ parametrical sketches and models in the KOMPAS-3D system are offered. The content of the developed test tasks is based on analysis of 3D simulation’s stages within which novice users allow maximum number of wrong or far from optimum actions. In the test task on rational construction of parametrical sketches it is necessary to choose commands from the submitted lists for creation of the shown sketches. Tasks on solid-state simulation for details are based on the analysis of a form of fifteen models shown in axonometric projections. It is offered to optimize simulation procedures and to specify a minimum number of forming operations for creation of shown details models. Tasks on solid-state models editing show a multivariance of procedures for models creation and editing; these tasks have been directed to the rational choice for the minimum number of the forming operations for models modification. In a task on kinds insert in an associative drawing it is offered to make for the details shown in axonometry a right choice on number and content of necessary images in the associative drawing. In a test task on solid-state simulation for two-component assembly units is required to choose from a presented set of separate components the ones which are necessary for subsequent mental conjunction by executing the command “components’ side coincidence”.

Инженерная компьютерная графика (ИКГ) является одним из наиболее интенсивно развивающихся направлений технических знаний. Это нашло отражение в достаточно успешном внедрении в последние годы информационных технологий в преподавание ИКГ [6]. При изучении ИКГ используются CAD-системы (Computer Aided Design — конструирование, поддержанное компьютером) и методики, учитывающие современный подход к автоматизированному проектированию изделий, когда конструкторская документация создается на основе твердотельного моделирования этих изделий [4; 5; 7–10].
