Class I - Technical Illustrations

3.2.1.1. Information requirements and data functionality. Two dimensional geometry and text annotation form the majority of data items although some non-geometric information is required as well. Information requirements for this application subset include (but are not limited to):

- Simple two dimensional geometry in the form of lines, circular arcs, conic arcs, and spline curves.
- Non-geometric attributes of line weight and line font.
- Text annotation.
- Data relationships, including the concept of subfigures.
