MODELING AND DESIGN OF DRAWINGS OF PARTS WITH ELEMENTS OF SPLINES JOINTS IN AUTODESK INVENTOR PACKAGE

The work continues the previous research and developments on expanding the capabilities of computer modeling and adapting the tools of relevant software packages (primarily Autodesk Inventor) for the development of design documentation in accordance with the requirements of current standards. The purpose of this work is to develop and implement such tools into design and training practice that would simplify the designation and display of common structural elements of parts in accordance with modern requirements for models. In particular, according to Model-Based Definition (MBD) technology, it is an approach to creating 3D models in such a way that they contain all the data necessary for their manufacture and control. With MBD, the model becomes the source document that guides all further engineering activities. This paper discusses and proposes possible solutions for the design of spline elements, primarily for the semi-automatic display of their main parameters in the notation both on the model and on the drawings. Another aspect of the work is related to the automation of construction a simplified display of these structural elements (a similar approach can also be applied to gear joints) on drawings. To solve the tasks, the capabilities of the built-in programming language iLogic/VBA/VB.NET and the study of the database of models and assemblies with the corresponding elements were used. The developed tools were tested during classes with students and their convenience was proved.
