Abstract
The adoption of Virtual Reality (RV) technologies in prototype design and process revision has contributed to multiple industry areas. Nonetheless, the development of VR systems for engineering is a complex task, as it involves specialized teams handling low-level code development. Given these problems, the goal of this study is presenting a methodology for designing VR, through an Authoring System based on Computer-Aided Design (CAD). The presented methodology provides an easy integration of electric power substation floor plans and Virtual Reality software (VRS), as well as three-dimensional and symbol modeling conventions. Centralized software architecture was developed, composed of the CAD Editor, input manager and VRS. The methodology was evaluated through a case study applied to the conception (elaboration) of electric power substations (EPS) as part of a Research and Development (R&D) project for training and field assets supervision. The results demonstrated visual precision and high integrity in elaboration of a VR environment from the CAD floor plan. This work also presents a comparative analysis between manual conception and the Authoring System.
Highlights
Accepted: 4 November 2021The application of Virtual Reality (VR) techniques has improved many processes in multiple industry areas
Virtual Environment Manager (VEM): server responsible for storing the necessary virtual assets (3D models, Computer-Aided Design (CAD) symbols, etc.) and manage the information between the CAD Editor and the Virtual Reality software; CAD Editor (CADE): is the software used for the design and customization of floor plans
Project Management: routine activities such as user authentication to VEM, selection of user floor-plan design, configurations of element levels and store version history of actual floor plan; Symbol Manipulation: search, insert, edit, substitute, erase, move, rotate and scale the symbols that represent 3D models of assets; Asset Identification: attribute the code to the symbol when the Virtual Reality software (VRS) is destined to supervision of field assets
Summary
The application of Virtual Reality (VR) techniques has improved many processes in multiple industry areas. Construction industries employ VR technologies in design and processes revision associated with Computer-Aided Design (CAD) [1]. VR is an advanced interface for computer applications that allows users to navigate in real time in three-dimensional (3D) environments with multisensory devices for activation or feedback [3]. It provides a high level of immersion and fidelity in the representation of information [4]. VR is currently one of the most important areas emerging in computer technologies [5]
