The Inventor book was written with competency based modules. What that means is that you have not completed each module until you have mastered it. The Competency Test module contains multiple choice questions and a comprehensive lab exercise to test your mastery of the set of modules that you completed. There are no answers or keys supplied in a Competency Test module since it is meant to be checked by your instructor. If there are any parts of this module that you have trouble completing, you should go back and reread the module or modules containing the information that you are having trouble with. If necessary, redo as many lab exercises required until you fully understand the material.

If you are Completing this book:

• Without the aid of an instructor, complete the written test and the lab exercise.
• In a classroom with an instructor, the instructor will give instructions on what to do after you have completed this module.

Lab Exercise 6-1

Time allowed: 60 minutes.

Step 1

Start a new part file with the template: English- Modules Part(in).ipt, and save the file with the name: Inventor Lab 06-1, as shown above.

Step 2

Project the Center Point onto the Base sketch.

Step 3

Draw the Base sketch for the object shown in the figure and apply all of the necessary geometrical constraints to maintain the shape of the sketch. Note the location of X0Y0Z0. (Figures Step 3A and 3B)

Step 4

Insert the necessary driving dimensions to fully constrain the sketch. Add at least 1 driven dimension.

Step 5

Ensure that the sketch is fully constrained and all lines display purple. (Figure Step 5)

Step 6

Extrude the sketch to complete the Base model and apply the color: Aluminum – Flat (Figure Step 6)
