Orthographic Drawing
Points are projected to the glass plane
defining the shape of each view, as
indicated by the blue lines
Projection Plane
The layout as shown here
allows for projecting between
views as illustrated by the blue
lines
Three major views are
Front, Top and Right Side
Measuring
Figure 29 Step 2
Step 2 From the first line measure up 3” defining the height of the front
and right side views, remembering to use light construction lines.
Figure 30 Step 3
Step 3 From the second line measure up 1” which defines the space between
views as well as starting to define the top view.
Figure 31 Step 4 Now measure up 2 inches from the third horizontal line for the thickness of with of the object, and draw the forth horizontal line as shown in Figure 31. This is the last horizontal line you will need to draw for this project.
Figure 31 Step 4 Now measure up 2 inches from the third horizontal line for the thickness of with of the object, and draw the forth horizontal line as shown in Figure 31. This is the last horizontal line you will need to draw for this project.
Figure 32 Step 5 You are now ready to draw the first vertical line, the line that runs form bottom to top of your sheet of paper. Measure in two inches from the left border line and draw your first vertical line with the aide of a T square and triangle. The line should be drawn from the first horizontal line to the forth horizontal line as shown in Figure 32. Be sure to use you 4H pencil for this construction line drawing very light.
Figure 33. Step 6
Step 6. In this step measure four inches to the right of the first vertical line and
draw a second vertical line from the from the first horizontal line to the forth
horizontal line as shown in Figure 33. You now have both the front view and the
top view of the object completed.
