This lab is used to teach you how to use Lego CAD. Lego CAD is a program that has all the parts ever made in legos. You put parts together to make a machine, landscape, or whatever you want to create with legos. It is basically a layout for what you want to build. You find the parts in real life after building it on the program, and then you can put it together with the program as a guidline or blueprint.
