Creating group drawings for the same type of products in the Autodesk Inventor program environment

Abstract

This article describes an algorithm for constructing models of the same type of parts with the subsequent execution of a group drawing and a detailed description of all operations and commands performed in the Autodesk Inventor environment. Information is provided on the design of group drawings in accordance with the standards of the Unified System of Design Documentation. In mechanical engineering, there are products that include several parts of the same type that have common design features. In order to reduce the total volume of design documentation when developing a group of products with common design features, it is necessary to carry out common group and basic design documents for such products instead of single documents for each execution of a product from this group. Thus, as a result of reducing the costs of drafting, manufacturing and registration of working drawings, the economic efficiency of unification and standardization of design documentation is achieved. The group design document contains permanent data reflecting the general design features of a group of products, and variable data characterizing some differences of products in this group. The rules for the execution and handling of group and basic documents are established by GOST 2.113–75. Products for which one group main design document (a group drawing of parts or a group specification) is executed are considered as a group of designs. At the same time, it should be possible to independently manufacture, use and account for each execution. For such parts, it is advisable to perform one group drawing containing all the necessary information about two or more such parts. A group drawing of products significantly reduces the number of technical documents and allows you to speed up the release of a set of drawings. The article presents the rationale for the introduction of such graphic works for students studying the course of engineering and computer graphics.
