alphabet of lines and different kinds of line in technical drawing

1. Kinds of lines in Technical
Drawing

2. The lines in the Alphabet of Lines are used to
described shape, size, hidden surfaces, interior detail, and
alternate positions of parts. Each conveys a particular
meaning on the drawing.
In the Alphabet of Lines thick, dark lines represent
the outline of an object, showing its visible surfaces and
edges. Thinner construction lines show the placement of
construction layout work. Short dash lines represent
nonvisible surfaces. A phantom line is a long line followed
by two short lines. This line shows the alternate position of
a moving part.

 The Alphabet of Lines is a list of
line symbols that engineers use in
technical drawings to
communicate specific shapes
,sizes or surfaces. The lines and
symbols used in the Alphabet of
Lines are universal, which means
engineers around the world used
and understand them.
