This video show how to complete Assignment 5 from Tutorial 1-8.
This video shows some new tools that aren't used for drawing, but rather for annotation.
These tools are extremely important as they will convey the information to the person reading the drawing. A drawing without dimension can't be read by anyone unless they have a CAD program. Think of shop drawings, blueprints, etc that end up in the hands of the people building the things you design. You want to provide them with as much information as possible to make their job easier and avoid questions coming back to you.
