Part of Unit: Multi-View Drawings
Lesson Plan Overview / Details
In this lesson students will be able to develop a fully dimensioned multi-view drawing from a handout. They will develop the drawing given two of the views along with an Isometric. They are required to create the third view and dimension all three views, using AutoCAD software and will understand the use of multi-view applications in the Engineering Design industry.

Objectives and Goals
- layout basic multi-view drawings (top, front, end views)
- redraw top and front views
- generate and complete the end view of the multi-view drawing
- understand the rotation of an Isometric view
- understand how multi-view applications are applied in industry
- understand how multi-view applications are required to meet industry standards
Activities in this Lesson
- Video / Lecture - Hooks / Set
Students come into the classroom. While they are coming into the classroom and getting their handouts and scales the video will be playing on the screen. The video "Plant Engineering - Fast Shop Drawings" will show the students the capability of using CAD to create multi-view drawings from a solid model. I then explain to the students the reasoning for multi-view drawings and the need for them in developing products. Once we get to this point I actually do a CAD demonstration on how to actually create the particular drawing the students will work on. This allows the students to use prior knowlegde in dimensioning, basic CAD drafting, text placement and general layout parameters
- CAD Lecture - Lecture
Students are informed they are given one class session to complete the multi-view drawing. Students are given the rubric on how the project will be graded and the criteria for grading. General layout will be referenced (prior knowledge) on colors to be used for drawing. Printing is color dependent (this is how printing is applied in the industry) so the need to draw in the proper colors and linetypes and the meaning of those colors and linetypes.
- Project Layout by Instructor - Demo / Modeling
I inform the students that I will now create the project on the computer. I give them line types, line colors, layers and the line type scales to be used in the project and the importance of these applications and how the colors may change from office to office in the industry however the line types will be a constant. All have been done on a previous "Title Block Drawing." So for the students they just have to open the "Title Block" and begin following along. I initially layout the two views that are given to the students. Starting them out by drawing rectangles and then adding circles where needed and any additional lines. Once completed with the layout then the project is dimensioned and any additional text added. Students follow along and ask questions as we are going thru the first of the 3 views. Once the first two views are completed, I then sketch the third view on the white board, and explain to the students how I derived the additional view.
- Individual Practice - Lab / Shop
Students continue from the intial layout of the first view and on there own they will create the other two views. As they are creating the views I walk around class and monitor them individually. This allows me to assist them and verify if each student is getting understanding of the concept.It allows the students to ask questions and it allows me to monitor their progress individually.
- Closure / Preliminary Printing - Closure
Students will print their drawings on 8-1/2"x11" and then I individually review each of the drawings with the students. I then allow them to go make any modifications to correct the drawings prior to final print. We can discuss the basic development as well as why the drawing is incorrect. It gives the students one on one and the the opportunity to correct the items.
