INTRODUCTION TO PRINT READING

Introduction To Print Reading DOE-HDBK-1016/1-93 INTRODUCTION TO PRINT READING INTRODUCTION TO PRINT READING A through knowledge of the information presented in the title block, the revision block, the notes and legend, and the drawing grid is necessary before a drawing can be read. This information is displayed in the areas surrounding the graphic portion of the drawing. EO 1.1 STATE the five types of information provided in the title block of an engineering drawing. EO 1.2 STATE how the grid system on an engineering drawing is used to locate a piece of equipment. EO 1.3 STATE the three types of information provided in the revision block of an engineering drawing. EO 1.4 STATE the purpose of the notes and legend section of an engineering drawing. Introduction The ability to read and understand information contained on drawings is essential to perform most engineering-related jobs. Engineering drawings are the industry's means of communicating detailed and accurate information on how to fabricate, assemble, troubleshoot, repair, and operate a piece of equipment or a system. To understand how to "read" a drawing it is necessary to be familiar with the standard conventions, rules, and basic symbols used on the various types of drawings. But before learning how to read the actual "drawing," an understanding of the information contained in the various non-drawing areas of a print is also necessary. This chapter will address the information most commonly seen in the non-drawing areas of a nuclear grade engineering type drawing. Because of the extreme variation in format, location of information, and types of information presented on drawings from vendor to vendor and site to site, all drawings will not necessarily contain the following information or format, but will usually be similar in nature. In this handbook the terms print, drawing, and diagram are used interchangeably to denote the complete drawing. This includes the graphic portion, the title block, the grid system, the revision block, and the notes and legend. When the words print, drawing, or diagram, appear in quotes, the word is referring only to the actual graphic portion of the drawing. Rev. 0 PR-01 Page 1
