Chapter 3: The Lines and Views of Manufacturing Prints

Introduction

Two items will be reviewed in this chapter: the lines of prints and the views of prints.

The lines that are used to make drawings are not all the same. Different types of lines are used for different purposes. Solid lines are used to show the shape of the part. Dashed lines are used to indicate features that are not visible.

The views that are shown on prints are arranged in a specific way. There are also several different types of views that are used for different purposes.

A detailed examination of lines and views will make print reading much easier.

It will be much easier to understand the subjects in this chapter if the worksheets are completed after each subject in the text. As an example, after reviewing the text on lines, complete the worksheets on lines. The worksheets are identified after each subject. This method will make Chapter 3 much easier to understand.
