I have sent my final project for my Introductory (100 level) Graphical Communications
class for this semester.
Students in this class are first semester freshmen with little no drafting experience and no
CATIA experience.
This final project is the capstone for the course. They are given the last 4 weeks of the
semester to complete the project, this is in addition to the regular course work. At that
point in the semester students have been taught all of the skills listed below, they must
utilize them to successfully complete the project. Students are to complete the project
outside of class time. They may visit me during my office hours or the CATIA lab tutors
for help or to ask questions.

Final Project
Belt Tightener
Due Tuesday the 30th of November 2006
Part I – 50 Points (Modeling)

Create solid models of the following parts:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Frame
Pulley
Bracket
Washer
Shaft
Pin
Bushing
#406 Woodruff Key
Hex Nut
All parts are to be created from within the assembly design bench. You must rename your
branches in the specification tree to match the part names.
All sketches are to be properly constrained.
Belt Tightener is to be completely assembled within the assembly design workbench,
using constraints.
Create a Folder called your last name Belt Tightener
When saving from within the assembly design workbench, YOU MUST USE SAVE
MANAGEMENT. The command is found under the pull down menu: file/save
management.
REMEMBER TO SAVE, SAVE OFTEN, AND TO MULTIPLE LOCATIONS.
Place all of the files in the folder that you renamed: your last name Belt Tightener.
 There will be 10 (ten) part files (plus your A and B size drawings) in this
directory:
o One product file renamed to your last name Belt Tightener
Assembly.CatProduct
o 9 (nine) part files named:
1. Your Last name Frame
2. Your Last name Pulley
3. Your Last name Bracket
4. Your Last name Washer
5. Your Last name Shaft
6. Your Last name Pin
7. Your Last name Bushing
8. Your Last name #406 Woodruff key
9. Your Last name Hex Nut

There will also be all associated drawings this is folder:
You are to submit these files to me via CD, and only on a CD, clearly labeled with your
complete name, class and section.
You will be graded on the quality of the modeling process for all of the solid models, i.e.
number if steps, extra sketches, part orientation, accuracy of the solid models, etc.
You will be graded on the quality of the final CATIA assembly, i.e. the number of
constraints required, proper orientation, quality of fit and alignment, ability to follow
provided instructions, etc.
Part II – 50 Points (Documentation)
B Size:
 Assembled Drawing of the Belt Tightener (Isometric View Only)
o With Completed Title Block and Parts List
o Each Part is to be clearly identified with a parts bubble
o Sheet Number (1/X)
o Save the drawing using save management
o Print one copy of the drawing.

Exploded Assembly Drawing of the Belt Tightener (Isometric View Only)
o With Completed Title Block and Parts List
o Each Part is to be clearly identified with a parts bubble
o Sheet Number (2/X)
o Save the drawing using save management
o Print one copy of the drawing.
A Size:
 For all drawing listed below include the following:
o Complete Title Block
o Most Appropriate scale
o Required Orthographic Views
o Proper Orientation of Iso View
o All Proper Lines Provided
o Change the sheet to reflect the proper number in the drawing sequence.
(3/X-X/X)
 Standard documentation of the Frame (3/X)
 Create a second drawing that has the most appropriate
(descriptive) section view plus required orthographic
views. (4/X)
 Standard documentation of the Pulley (5/X)
 Create a second drawing that has the most appropriate
(descriptive) section plus the required orthographic views.
 Standard documentation of the Bracket
 Create a second drawing that has an auxiliary view plus the
required orthographic views.
 Standard documentation of the Washer
 Standard documentation of the Shaft
 Standard documentation of the Pin
 Standard documentation of the Bushing
 Standard documentation of the #406 woodruff Key
 Standard documentation of the Hex Nut
o Save each Drawing using Save Management
o Print 1 Copy of each Drawing
You are to place the printed drawings (in order) in a folder. A portfolio folder, (no 3 ring
binders, please)
Provide a cover sheet with your complete name, class section, belt tightener, and a list of
all the provided drawings (in order)
You are to neatly secure the CD to the folder, in such a way that it can be easily removed
and that will not damage the CD or folder when removed.
You will be graded on the overall quality (readability/presentation) of the drawings,
appropriate scale, view selection and orientation, your ability to follow provided
instructions, etc.
The final project (hard and electronic copy) is due on the 30th of November 2006, at the
beginning of class. Projects turned in late will be marked down 30%, there are NO
