IMPROVEMENT OF CONSTRUCTION OF THREE-DIMENSIONAL MODELS AND PERFORMANCE OF DRAWINGS OF COMPRESSION SPRINGS IN THE AUTODESK INVENTOR PACKAGE

Abstract

The work offers developments that complement the functionality of the Autodesk Inventor package, reducing the time for designing three-dimensional models and making drawings in accordance with applicable standards.

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

The solution to the problem was carried out using the capabilities of the Autodesk Inventor package - the iLogic subsystem. The proposed solution is based on creating an iLogic rule for the compression spring model. Templates were developed for the operative interaction of the designer with mechanical engineering CAD.

Compression spring geometry is entered as constructor parameters. 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 specifications. Parameter shapes reflect their properties in a separate window of the part file.

To optimize the design of design documentation, a drawing template was developed, which was developed with the ability, in an automatic mode, to visually display technical requirements and numerical values ​​of numerical parameters and a text description of text parameters using the properties of a three-dimensional model of a compression spring. For this, the technical requirements forms and variable identifiers are reflected in the sketch symbols. When you place a 3D model of a compression spring on a template format, export of its properties is automatically activated.

The proposed developments reduce the design time 3D model of compression springs with the visualization of technical requirements when making drawings in accordance with applicable standards.

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