Learning Activity

General Objective: To introduce new CAD commands, OFFSET, RECTANGLE, COPY, MULTICOPY, MIRROR, TRIM, and MOVE. Students will understand methods of duplicating existing entities with correct usage of new and previously mastered commands on AutoCAD

Behavioral Objective(s): Upon completion of today’s lesson, students should be able to:

1. Determine and set OBJECTSNAP commands.
2. Use ORTHO mode to draw straight lines if necessary.
3. Enter coordinates and numeric conversions correctly.
4. Use OFFSET, RECTANGLE, COPY, MULTICOPY, MIRROR, TRIM, and MOVE commands to assist in completion of Complex Drawing drawings.

Supplemental Activities and Suggested Resources:

Compare previously mastered commands with new commands and determine which commands accomplish the same goal with fewer steps. Determine which commands allow the designer to complete a drawing more efficiently and accurately.

Assessment

(Student Self-Assessment, Student Assessment of Instruction)

Note to Instructor: Students may use this instrument or he/she may be directed to a site where an Online Assessment instrument is provided. Click here to access the Online Assessment instrument.

Directions: Considering today’s lesson, respond to the following by answering yes or no. If necessary, provide a brief explanation for items that request an explanation.

Student Self Assessment:

• Did I remember when it is appropriate to use ERASE versus TRIM command?
• Did I understand when it is appropriate to use COPY versus when to use MIRROR?
• Are my drawings 100% accurate, according to the solution posted?
• Was it possible for me to produce accurate drawings quicker utilizing new commands?
• Did I labeled and saved my drawing to the hard drive?
• Am I able to produce other drawings utilizing new and previously taught AutoCAD LT commands, information/instructions in Chapters 1-4 of the Mechanical Drawing textbook, and by using instructional handouts?
• Are my drawings completed faster and more accurately using the new commands?
• Is knowing how and when to use certain CAD commands important for designing and creating technical drawings? If yes, briefly explain.
• Will the new commands that I learned today allow the graphics language to be more effectively communicated to others?

Student Assessment of Instructor:

• Were the commands covered today presented in an easy-to-understand sequence that allowed me to become familiar and comfortable with the software?
• Was the information presented today covered today presented so I could build on what I learned during previous lessons?
