This was oblique drawings... we worked alone. We learned how to make it porportional and began shading.
The oblique sketch, begins with a straight on view of one of the objects faces. Ithis view shows the objects width, and height. In this view, the depth can be any size and drawn at any angle.

Isometric pictorials were equally measured. They all share the same point, and represent height, width, and depth. Perspective sketching has up to three point perspectives. One point perspective has one vanishing point, two point perspectives have two vanishing points, and three point perspectives have three vanishing points.

Multi-view drawings show two or more two- dimensional views of a three dimensional object. This has about four view of an object all in the same page.
