Abstract
As modern industry expands towards an "extended enterprise," interaction between engineers and computer systems and among designers over networks is becoming increasingly important. This work introduces a new interaction method that makes it possible to convey three-dimensional geometrical information by means of freehand sketching. Using this approach, designers will be able to interact faster, more naturally and more fluently with their CAD systems and with other remote designers over a network. This capability will be particularly advantageous at the conceptual design stages, where qualitative information must be communicated without the accurate details often required by today's CAD systems. This paper describes the basic concepts of the proposed interaction methodology and the principal algorithmic aspects of its implementation. Examples from a working system are shown.
