• Cutting Pumpkin - Hooks / Set

  This unit usually takes place around Halloween for me but the hook set is more the discussion that takes place along with having something real to handle it could be pumpkins, donuts, a light switch, an old guitar or whatever you think would get your students interested in the discussion. (40 - 50 min.)

• Section Views Power Point - Lecture

  With the aid of the Section Views Point Poinl views are explained.   All section view types should get full attention; the cutting plane fully explained; and conventional representation covered in detail.,   It is anticipated that the students will  take notes (50 min) so one must proceed slowly to give the students full opportunity to take good notes and sketches  The instructor shuld announce. to the students that the instructor will collect and review the notes wit attention to the definitions of  the various section views and the sketching results.

  • INTRO_Sectional_Views.ppt [ Download ] Power Point with many images downloaded from the web. This is meant to be an introduction to Section Views and can be difficult to get through in a one hour class. There are 26 slides but I only focus on the first 18 with first year students
• Hand Sketching & CAD Drawing - Demo / Modeling

  I use a camera projection as I sketch at my desk (a whiteboard works) as I demonstrate a simple full frontal section, working at a slow pace through a step by step process - known as guided practice.  (20 min for hand sketch) (20 min for computer sketch)

  1. Draw top & Front side views (when we hand sketch it is not to scale)

  2. place the cutting plane line (CPL) in the Top side view.  Placement is the center of depth and all along the width. (Explain that the front half of the top view will be discarded so that when we look at the front plane the inside will be revealed.)

  3. (For this part) we change all of our  hidden lines to object lines

  4. Apply section lining on any surface that touches the cutting plane.

  Upon completion students work on their own, drawing the part using CAD software to make principle views, When students are ready I begin a demonstration to show how to make Section Views by either changing the front side view (in AutoCAD) or replacing it. (Inventor & SolidWorks)

  For students that are not ready for this demonstration I download a file to follow along with.

  Three worksheets are passed out to students (each sheet progressively becomes more difficult)  Students are expected to work on the hand sketching of  these outside of class then choose one part from each sheet to create the part and drawing files in class.  Each worksheet is 10 pts. and the printed CAD drawings are also 10 pts. each.  If you need the answers e-mail me as I got these from Nor Cal and do not want to post the answers to their worksheets.
