Exploration and Evaluation of CAD Modeling in Virtual Reality

Seth M. Freeman, Landon Wright, John L. Salmon, Brigham Young University

Abstract. Current commercially available computer-aided design (CAD) software is limited to interfacing with the user at a computer terminal using common peripherals, such as a mouse and a keyboard, to interact with the software through windows, icons, and menus.  While this method is effective and allows for the rapid transfer of ideas from the user to the computer, there exist methods of altering the traditional workflow that can enhance the user experience. For example, extensive work has been done to allow multiple users to interact with the same virtual model at the same time. Similarly, virtual reality (VR) has been explored to aid in the review process of CAD models.  The task of creating and editing CAD models from within a VR environment has also been researched to some extent. The objective of this research was to develop and test a proof of concept for VR software that would programmatically create BREP models in a traditional CAD system through the use of the developer’s application programming interface (API). Through the application of this API, it is possible to rapidly create geometry in the VR environment that can then be parametrically edited and refined in the CAD software through the traditional terminal interface with all the supported windows, icons, and menus.

Keywords. Virtual reality, modeling, user testing, proof of concept, 3D printing, rapid prototyping
