Step Four Complete the isometric rectangular solid by sketching the top, back edges parallel to the two edges you drew In step three... 

Sketching Complex Objects in Isometric So far you have learned to sketch simple isometric shapes such as rectangular solids, circles, arcs, and cylinders. You also learned to sketch inclined planes, or planes that are not perpendicular to the six normal planes (front, right side, top, left side, back, and bottom). Now you will take what you have learned and combine shapes to create recognizable objects. 

AU objects can be divided into simple isometric shapes. The best way to do this is visualize each part of the object as a rectangular solid. Once you have accomplished this, you can begin to add curved shapes such as circles, arcs, or cylinders. Figure 5-16 shows you a step-by-step process. 

Using correct freehand technical sketching techniques, practice sketching isometric rectangular solids. See Figure 5-30 for a practice example.

Directions 1. Using a practice sheet from your teacher, sketch isometric rectangular solids by re-drawing the rectangular solid shawn in this example at the pre-marked locations.
