AUTOMATION OF DESIGN DOCUMENTATION OF TENSION SPRINGS IN THE AUTODESK INVENTOR PACKAGE

Abstract

The paper offers developments that complement the functionality of the Autodesk Inventor package, reducing the time required to design three-dimensional models and execute drawings in accordance with current standards.

The developments are demonstrated by the example of automation of design documentation when creating a three-dimensional model and drawings of the tension spring.

The problem was solved using the capabilities of the Autodesk Inventor package - the iLogic subsystem. The proposed solution is based on the creation of the iLogic rule for the tension spring model. Templates were developed for the operational interaction of the designer with the machine-building CAD.

The geometric characteristics of the tension spring are introduced as the parameters of the constructor. For visual perception of graphic information, each parameter is assigned a variable identifier with export activation. The iLogic rule is created for parameters that are used in technical requirements. The parameter forms reflect their properties in a separate window of the part file.

To optimize the design documentation, a drawing template was developed, which was developed with the ability, in automatic mode, to visually display technical requirements and numerical values of numerical parameters and a textual description of textual parameters using the properties of a three-dimensional model of the tension spring. For this purpose, the forms of technical requirements and variable identifiers are reflected in the designations. When placing a three-dimensional model of the tension spring on the template format, the export of its properties is automatically activated.

The proposed developments shorten the design time of three-dimensional models of the tension springs with visualization of technical requirements when performing drawings in accordance with current standards.

The templates developed in the work are implemented in the educational process and can be used in mechanical engineering to optimize the development of design documentation at the design stage.
