Example 3.1
The engineering drawing shown contains at least five errors or items that are considered poor practice. Find these items and note, in your mind, how these items should be corrected.
rtions of the drawing may be enlarged by clicking on that area.
When checking another drafter's or engineer's drawing, you should not make the actual corrections, but rather indicate on the drawing what you believe the correction should be. There are sometimes special reasons why a drawing is done the way that it is. Only the drawing's originator would know for certain.
The paper is a non-standard size, and is incorrectly marked as A4.
The dimensions contains lettering of vastly different font sizes.
Standard sheet sizes have been established by ANSI for use with technical drawings. The American Standard sizes, dimensioned in inches, double in size from size A to size E. The International Standard sizes, dimensioned in millimeters, double in size from size A4 to size A0.

Working Drawings
Working drawings, unlike sketches, precisely describe a design without any supplementary explanation. Since the originator has no control over the drawings after they are completed, they must stand on their own without ambiguity.
Working drawings can be divided into four categories:
Shows how the components of a completed assembly fit together and function.
Layout
A dimensioned, multiview drawing of a single part.
Detail
An isometric drawing showing how assemblies or subassemblies are constructed.
Assembly
Catalogs the parts by name, number, and quantity, and lists the total amounts of each material used.
