Start the lower left corner of the front view
here, up 2 and over 6 lines
East High School Name
9
Each grid line is one quarter of an inch. So, you
need to count over 4-inches and draw the line
East High School Name
10
Since each grid line is one quarter of an inch,
you need to count up 2 1/2-inches and draw the
line.
East High School Name
11
Since the left side is 2 1/2 tall, count up 2
1/2-inches and draw the line for the right side
of the rectangle.

12
Now draw the final edge of the rectangle.

We want to start to draw the top view up, 1 1/2
inch from the top edge of the front view
East High School Name
14
Draw this line of the top view up, 1 1/2
inch from the top edge of the front view
East High School Name

For this edge of the top view draw a 2-inch line.

This edge of the top view is also a 2-inch line.

Now finish the top view and draw the final edge
East High School Name
18
Also we begin the Right Side View 1 1/2-inch
from the front view
East High School Name

Now, begin to draw the Right Side View 1
1/2-inch from the front view
East High School Name

Now, begin to draw this edge of the Right Side
View 1 1/2-inch from the front view. It is
2-inches long.

This edge of the Right Side View is also
2-inches.
East High School Name
22
Finish the right side view and draw the final
edge.

23
Now, If we want a hole in the front, we need to
draw the hole, 3/4inch in from each edge
East High School Name
24
And we need to draw hidden lines to show the
hole goes all the way through in the top view
East High School Name
25
And we want to draw hidden lines to show the hole
goes all the way through in the right side view
East High School Name
26
Notice each end of the hidden lines needs to
touch each edge of the object. However PowerPoint
will not let me show this correctly

and stay ¼-inch Away from the edges
