Worldwide research has been carried out aiming at integrating VR technologies into CAD systems. Integration of VR technologies
into CAD systems is a complex process. In the majority of applications VR technologies are used for the visualization and
evaluation of previously generated CAD models [5, 7, 8]. The CAD system exports geometrical data to the VR system that is
used separately for immersive visualization. The ARCAD [3] system represents an example of the integration of augmented reality
into the AutoCAD system. The aim of this application is to use augmented reality technologies for the detailed visualization
and evaluation of the layered CAD model in the real environment. While an HMD device was used to visualize the model, every
time the CAD model needs modifying, the user is required to return to the CAD system.
This paper presents another modality of CAD-VR integration, allowing the user to create and manipulate 3D AutoCAD models in
an intuitive and natural manner using VR technologies, and also offering the possibility of visualizing the 3D model within
the immersive virtual environment.
