DISCLAIMER:

2

The purpose of this sample exam is to show you the format and approximate difficulty level of the questions that you will find in the CATIA V5 Part and Assembly Design real exams. It is not meant to give away the whole exams content The questions are examples of what to expect in the following three areas: • Part Modeling • Assembly Creation • Drafting (there are Drafting questions in both Part and Assembly Design exams) Note that some data are provided to perform the Assembly

How to take this sample exam: 1. To best simulate the conditions of the real exam, it is best NOT to print this exam. Since the tester software window runs concurrently with CATIA, you must switch back and forth between the two applications. Keeping this document open and consulting it on your computer while running CATIA is the best method to simulate the real exam conditions. 2. The multiple choice answers should serve as a check for you to ensure that your model is on the right track while completing this exam. If you do not find your answer in the selections offered then, most likely, there is something wrong with your model at that point. 3. Answers to the questions are on the last pages of this sample exam document. There are also hints that can help you save time during the exam.

Question #3 - Part Modeling (Tool Block) Step One

5

Build this part in CATIA • • • • • •

Unit system: MMGS (millimeter, gram, second) Decimal places: 2 Part origin: Arbitrary All holes through all unless shown otherwise. Material: Steel Density = 0.00786 g/mm^3

• • •

A = 81.00 B = 57.00 C = 43.00

 What is the overall mass of the part (grams)? Hint: If you don't find an option within 1% of your answer please re-check your solid model.

Question #4 - Part Modeling (Tool Block) Step Two Modify the part in CATIA • • • • • •


Use the part created in the previous question and modify it by changing the following parameters: • A = 84.00 • B = 59.00 • C = 45.00 Note: Assume all other dimensions are the same as in the previous question.

 What is the overall mass of the part (grams)? ------------------------------------------------------------------

Question #7 – Assembly Modeling

13

Build this assembly in CATIA (Chain Link Assembly) It contains 2 long_pins (1), 3 short_pins (2), and 4 chain_links (3) • Unit system: MMGS (millimeter, gram, second) • Decimal places: 2 • Assembly origin: as shown on the image - Download the zip file (Chain Link Assembly) and open it. - Save the contained parts and open them in CATIA. IMPORTANT: Create the assembly with respect to the origin as shown in the isometric view. (This is important for calculating the proper Center of Gravity) - Create the assembly using the following conditions: 1. Pins are mated concentric to chain link holes (no clearance) 2. Pin end faces are coincident to chain link side faces • A = 25 degrees • B = 125 degrees • C = 130 degrees

 What is the Center of Gravity of the assembly (millimeters)? Hint: If you don't find an option within 1% of your answer please re-check your assembly a) b) c) d)

X= -26.43, Y= 105.31, Z= -25.26 X = -30.51, Y = -109.89, Z = -61.40 X = 54.22, Y = -17.48, Z = 59.22 X = -10.54, Y = -208.48, Z = -34.64


Question #8 – Assembly Modeling

14

Modify the assembly in CATIA (Chain Link Assembly) • • •

Unit system: MMGS (millimeter, gram, second) Decimal places: 2 Assembly origin: as shown on the image

Using the same assembly created in the previous question modify the following parameters: • A = 30 degrees • B = 115 degrees • C = 135 degrees  What is the Center of Gravity of the assembly (millimeters)? -----------------------------------------
