To make this drawing I took a guide bearing and rotated it 30 degrees back to the left and drew the bearing in calvalier view which is where it is rotated at a certain angle with a face perpendicular to your line of sight when you are looking at it.

To make this drawing I took a bell hub and make the top view of it.  I also made the keyway and scaled it to a 2:1 ratio.  I then made a section of it to show the inside of the bell hub.

This was the final project for my survey of engineering graphics class.  To make this drawing I had to draw an exploded isometric view of a clamp using polylines, lines and isocircles.  I also had to make an assembly section of the clamp and a parts list with the part number, the quantity of the part, what the part is, and the material it is made of.

During the course of this class I learned how to dimension in Auto-CAD, which is a computer tool to make drawings of objects, what cavalier and cabinet drawings are and the difference between them,  how to make one and two point perspective drawings, how to make auxiliary views, how to use a table to dimension objects, and make isometric drawings using Auto-CAD.  I also learned how to make a sphere in a isometric Auto-CAD drawing using two isocircles and a polyline.

I had trouble making the perspective drawings before I saw how to get the correct distance from the vanishing point, I also had trouble visualizing how to draw a development and how it fit together when folded.  When making threads I had trouble getting the minor diameter before I looked in the back of the book and found a chart for them.
