Skills Summary
You should be able to convert and interpret different coordinate formats used to describe point locations and be familiar with some of the basic geometry useful in creating CAD drawings. You should also be able to identify and sketch primitive shapes joined by Boolean operations. In addition, you should be able to visualize and sketch revolved and extruded shapes. The following exercises will give you practice using all these skills.
