Part of Unit: Sectional Views
Lesson Plan Overview / Details
Students are introduced to the concept of section views.
OBJECTIVE: By the completion of this section, the student will be able to create section views from the basic orothographic projections of front view, right side view and/or top view..
PRIOR KNOWLEDGE: Must already know how to read Multiview Drawings and have an understanding of projection and rotation of Monge’s Principle Views, and some knowledge of AutoCAD (or software).

- Be able to locate, Identify, Understand and create symbolic section lining &/or specific hatch pattern
- Be able to define and use appropriate types of section views
Activities in this Lesson
- 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.)
- Cutting Pumpkins.ppt [ Download ] Normal views of an object (Pumpkin) and the development of a sectional view of the same object (Pumpkin). Microsoft Internet Explorer4 PowerPoint - demonstrating cutting a pumpkin to develop a section view.
- 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.

- Hand Sketch 2 [ View Image ] [ Download Original ] Example of hand sketch w/ full Frontal View

- Independent study - Lab / Shop
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.
- Unit Review - Closure
Restate unit objectives (see above)
Clarify that they have been achieved and are building blocks for future lessons & final exam
- Assessment Types:
- Rubrics, Portfolios, Teacher-Made Test, Observations,
Notebook checks are conducted each grading period and are 10% of a students overall grade. There is also a portfolio assignment at the end of the semester which students will need to include section drawings. I do a verbal quiz using power point on Fridays and we go over it by having students grade each other's quiz .
