Abstract

This chapter focuses on construction lines. Dimensions are placed on a drawing with figures perpendicular to and just above the dimension line. The dimensions are read from the base of the drawing and from the right-hand side. When a drawing of an object is to be made, the number of views should always be kept to a minimum. When a drawing is made of a part of a mechanism, it is called a part, or detail drawing. If all the parts are fitted together and a drawing is made, it is then known as an assembly drawing or general arrangement. The chapter describes two types of radius corners: (1) the right-angle type and (2) the angle type. It presents a line-by-line construction for both types.
