Experience in Development of Translators for AP203 Edition 2 Construction History

Abstract

I have been using computers to help artists since the mid 1990s. My first collaboration was with wood sculptor Brent Collins, living in Gower, MO. It was prompted in 1994 by a picture of a small wood sculpture called "Hyperbolic Hexagon" (Fig. 1a) [2]. The loop of six holes and saddles is reminiscent of the central portion of Scherk's "2 nd Minimal Surface." This correspondence led to an interesting discussion and inspired us to explore what shapes might result, if this paradigm was extended to toroidal rings with a different number of holes, to higher order saddles, or to structures in which the hole-saddle chain was subjected to some longitudinal twist before it is closed into the toroidal loop.

“…In header section there is some information about the designer and the part that is drawn and in data section there is various information about the mechanical part. In this section There are Those information which is important for extracting physical features which will extract form entities and attributes and their relations [20]. Figure 2 indicates a sample file of STEP AP203 and the information in each section can be read by human or be as an input file for a program language.…”
