Part of Lesson Plan: Good Dimensioning Techniques #2: Follow-Up Assignment by Ben Orozco

Activity Overview / Details

• Ask the class to take out their Good Dimensioning Technique handouts that were given in a previous class. 
• Review with them the importance of following the correct processes to place dimensions on a drawing and how jobs and industry will not accept messy or inaccurate work. Remind students that accuracy on a drawing leads to accuracy on building a project which leads to a safe usable product.
• Now hand out the new information on Dimensioning Angles and Arcs. Have the students follow along as you read the information to them. As you are reading show them examples on the board that represent what you are reading. (Have a drawing on the board ahead of time that will allow you to show the examples). Draw the Dimensioning examples on the board for the drawing as you walk and talk the students through the handouts.
• Be sure to allow students to ask questions along the way.
• Keep everything neat and use different colors to represent various parts of the Dimensions.
• Complete the demonstration and ask students if they have any questions in regards to the various Dimensioning techniques.
• EXAMPLE drawings for board attached . AutoCAD 2005 & PDF files.
