Plan and a Plan Oblique of a Cube:
1. Begin by drawing the top view of the cube. This is a 4" square. This will serve as your Plan.
2. Begin the Plan Oblique by drawing a second square on its corner. With a triangle ruler set the square on a 45 degree angle, be sure to keep the measurements accurate. When finished it will look like a diamond.
3. With ruler, draw vertical, parallel lines from all corners that measure 4" up.
4. From the end point of the vertical left line use the Triangle Ruler to find a 45 degree angle and project it to the end point of the next line segment. Continue to connect line segments at 45 degree angles until the form is complete.
5. The Cube now appears transparent. Erase interior lines so the cube appears opaque.
