| SpaceCAD LESSON 10. Orthographic Projection of Space Shuttle Orbiter STEP 1. Drawing the body |
| Use a Grid
spacing of 0.125 and an A-size portrait sheet. The Grid
spacing will change a couple of times during the drawing.
First you need to draw the
body of the Shuttle. Use the Rectangle
Now draw the cockpit area. Use the Line command to draw a vertical line from the upper right corner of the rectangle, type in ".5" for Dist and "90" for Ang. Then use the Arc (Sp, Ep, Mid) command to draw from the top end of the last line you drew, so X = -0.5 and Y equals 1.5. The mid point should be at X=.375 and Y=-0.75. It will now look like this:

command. Near the center of the paper, type in
"1.5" for the X value and "4.625" for
the Y value of the Rectangle
command. Next draw a vertical line through the
middle of the rectangle. Draw the line going
through the entire paper. This is your "mirror
line". Nothing else will be drawn on the left side
of the line until after you mirror the entire drawing.
