Module Objectives
1. Differentiate the different types of sectional
views.
2. Create sectional views drawing from a given
isometric or oblique drawings.
3. Define hatching and explains it’s function
Introduction to Sectional Views
Introduction to Sectional Views
A sectional view is that view seen beyond
an imaginary plane passing through an object at
right angles to the direction of sight.
Sectional views are used to show the
interior construction or details of hidden
features that can not be shown clearly by
outside views.
Introduction to Sectional Views
The cutting plane on which a section has
been taken is indicated by a heavy dash line.
Arrow heads at the ends of the cutting
plane lines are used to indicate the direction in
which the sections are viewed.
See the following figures

Hatching
Hatching
Hatching lines are thin lines and should
preferably be inclining at 45 degrees. They
should be evenly spaced.
Hatching
If there are two or more adjacent sectioned
parts, the hatching lines should either be of
different spacing or different direction. See the
following figures.
However, hatching pattern should be the same
for separate areas of a single object.
