This document brings together the fundamental contents of application protocols (AP) developed by the Initial Graphics Exchange Specification (IGES) Organization and approved as American National Standards (ANS) by the IGES Product Data Exchange using STEP (PDES) Organization (IPO). This included APs are Drafting, Three-Dimensional Piping, and Layered Electrical Products. The combining of material from three APs provided a mechanism wherein information supplied redundantly within the separate documents can be included once. Examples include the definitions, and the common object models found in the Application Implementation Models (AIM). All of the material has been updated to be compatible with, and referenced to IGES Version 6.0. Internet-related entities have been introduced in IGES 6.0. Therefore a "Figure Viewer" drafting application for technical illustrations which would benefit Web-serving of vector graphic IGES files has been specifically defined to utilize these entities.
