Use the line and circle tool and positional coordinates to create the drawing. Pay attention to where your datum point starts. I use the corner that the most dimensions come from as my datum. This way it will make it easier to figure out what the coordinates are for the geometric features that have to be placed on the part.
Ask yourself the following on this drawing:
What is the best point to use for my datum (0,0) point?
Which draw tools will I use?
Will I use absolute or relative coordinates?
How can I draw this in the least amount of key strokes to be the most efficient?
