The Cutplane: a tool for interactive solid modeling

Content Provider	ACM Digital Library

Abstract	Today, most solid modeling systems are used only in the final stages of design, where iterations are driven by analysis rather than creative exploration of alternative solutions. These systems have complex interfaces, slow response, and do not provide a convenient way of specifying a three dimensional position using a two dimensional display screen. As such they are not viable alternatives to visualization methods traditionally used in early design.This paper presents a geometric modeling system which incorporates a new concept for intuitively and unambiguously specifying and manipulating points or features in three dimensional space. The central concept, the Cutplane, consists of a plane that moves through space under control of a mouse or similar input device. The intersection of the plane and any object is highlighted, and only this highlighted section can be selected for manipulation. Selection is accomplished with a crosshair that is constrained to remain within the plane, so that the relationship between the crosshair and the feature of interest is immediately evident. Although the idea of a section view is not new, previously it has been used as a way to reveal hidden structure, not as a means of manipulating objects or indicating spatial position, as is proposed here.
