Another important aspect of designing parts and solids is the ability to sketch out the different views of an object. Doing so gives observers a better understanding of a part, where the holes are, interior design, things like that.
And while it’s irritating, especially as the parts get more complicated, I can see how it would be quite important when you get a job and try to communicate with other engineers. Hence the course title, Graphics Communication.
Anyway, here’s a simple example of how we’d draw different views of a part. The first one, upper right, is the top view. The one below it is the side view. And the final one is the section view, where you cut the part open to see the inside. The location and viewing direction of the cut is indicated by the dotted lines with arrows on the top view.
