Yc. Yu et al., ED-DESIGN - AN ENGINEERING DRAWING BASED DESIGN-MODEL FOR COMPUTER UNDERSTANDING, Robotics and computer-integrated manufacturing, 10(3), 1993, pp. 169-183
Constructing a solid model through computer understanding of engineeri
ng drawings could resolve the input problem of solid models. For compu
ter understanding, however, the engineering drawing has to be defined
and represented with clear semantics. The conventional engineering dra
wing is usually described by showing examples and represented as a set
of curve segments on a drawing plane, so that it can only be understo
od by human engineers. In this paper, an engineering drawing based des
ign model, ED-DESIGN, which is much more computer understandable than
the conventional one is proposed. In this model, an engineering drawin
g is represented in a drawing space rather than in a drawing plane. In
other words, the scheme of engineering drawing is interpreted as a ps
eudo-3D surface design scheme rather than a 2D design scheme. With thi
s design model, it is possible to develop definite knowledge for const
ructing a solid model through computer understanding.
