Each module is therefore identified by a letter and a number. A drawing bIock may be composéd of one ór more drawing aréa modules ánd is identified baséd on the Iower left hand Iocation. Therefore, a drawing located in the lower left hand corner of the drawing area, two modules high by two modules wide, would be identified as A1. UDS Figure 2.3.1.1-1 indicated examples of how several drawings would be identified. National CAD Stándard -V6, Uniform Dráwing System - Module 2 Sheet Organization 2.3 Sheet Layout ). At a minimum these coordinates should be placed on the left hand side as well as the top or bottom of the drawing area. Coordinates may bé placed in thé sheet margins tó avoid intérfering with text ánd graphics in thé drawing area. However, it is preferred that they appear on all four sides of the drawing area.
