    MAE 110 Engineering Graphics

    Design Project Solid Edge

    A design project is assigned to give each student the opportunity to showcase their ability to think and process graphic information in three dimensions via the construction of objects in Solid Edge. Although there are many steps to a complete product design, this project focuses on the mechanical design and drawing aspects of the design procedure.

    Project Requirements

    1. Choose your topic based on something you enjoybe it related to your career choice or perhaps a hobby,

    previous work, etc., subject only the following limitations:

    a. No weapons of any kind whatsoever. Definition of what constitutes a weapon is the sole discretion of

    the instructor.

    b. No devices designed for use in illegal activities of any kind whatsoever. Definition of illegal activities

    is the sole discretion of the instructor.

    c. Your topic must be something that is capable of being conceptualized, analyzed, designed, and drawn

    in Solid Edge within the time period allotted.

    2. Place all your parts in one folder named by the convention ―yourlastname-project1.‖

    3. Use at least one of each kind of extrusion: (linear) extrude, revolve, loft, and sweep. The revolve, loft, and

    sweep should not be done when another extrusion would do the job better. As an example, do not sweep a

    straight cylinder or loft a flat plate. You will receive no credit if these extrusions are used improperly.

    4. Use at least one of the 3D geometric features such as thin wall, round, chamfer, etc…

    5. Use only one assembly (that means there should be no sub-assemblies). Note that there must only be one

    ―ground‖ in the entire assembly.

    6. There must be no interference between any two parts.

    7. Each part must be fully constrained.

    8. Minimum part count requirements are twenty (20) unique parts.

    9. If you have to ask if a part is ―unique enough,‖ then it is not. Parts which are too similar will NOT be counted as

    unique parts.

    10. Due dates are listed on the ―Schedule‖ handout.

    11. A Proposal, Design Review, and Final Report are due on the dates listed in the ―schedule‖ handout and listed

    below.

    Proposal (10 points): Due 2/6

     This is a one-page description of what you intend to do, why you have chosen it, and roughly how you expect to draw it. It should be at least 3 paragraphs long, and include a sketch or picture to make perfectly clear what your

    design project is all about. The content should include a general idea of where you plan to use your different types. It should also include a discussion about your construction procedure; what gets built first and last, explain the reasoning. See below for memo format.

    Design Review (10 points): Due 2/20

     This is a one-page description of what you have done so far. It should recapitulate your original proposal and, especially, point out any changes made to it and why. Any difficulties encountered so far, along with several alternative solutions, should be discussed at length. It can be three to five paragraphs long, and is in general, to be considered a combination progress report and ―coming soon.‖ Specifically mention the number of parts you have

    completed and the status of your assembly. See below for memo format.

    Final Report (10 points): Due 3/3

    This is a one- or two-page description of what you accomplished and what lessons you learned. Pay careful attention to how it correlates to you original proposal and your design review. It should be from five to seven paragraphs in length, and should explain the procedure you followed completely from start to finish. See below for memo format.

    Attached to this description will be a landscape printout from the drawing environment of your final, entire assembly. The required views are the four principal views we’ve used throughout the entire course.

    In addition to the paper-based submission of the Final Report, you will do a short presentation to the class as discussed below in the grading section.

    Report Format

    ; Spelling, grammar, and neatness all count.

    ; Do not exceed page limits. If necessary, use a smaller font, but don’t go smaller than 10-point. Keep your

    margins no smaller than 1 inch.

    ; Use standard memo format, which means you need each of the following on a separate line on the left

    margin ) use tabs as necessary to make things line up correctly):

    To: Me (include email address)

    From: Your full name (include email address)

    Subject: what you’re giving me

    Date: the due date

    ; Use separate paragraphs nothing makes a paper more difficult to read than to dump everything into one

    solid paragraph. If you have difficulty with this, or with using correct spelling and grammar, you should

    consult the Writing Center in Morton Hall (x6592.)

    ; If you forget to include your email address do not write it in with pen or pencil. Take the 5 seconds to

    reopen the document (you saved it right?) and type it in.

    ; Backup your proposal. If it is done incorrectly you may be required to do it again. Failing to back it up or

    not keeping an electronic copy handy means you will have to rewrite the entire thing.

    ; I recommend using one of the built in memo-wizards in MS word. Many of the requirements for your memo

    are built into that program.

    Presentation

    a. Before the presentation:

    i. Adjust the zoom to show your model at maximum size.

    ii. View your model in the isometric view and turn on shading.

    iii. Save your assembly, and then make a copy onto a USB drive.

    iv. ENSURE that you copy ALL OF YOUR FILES. Place them in a folder which contains YOUR

    LAST NAME. Try opening your assembly on a different computer than you normally use to

    be sure it will open correctly during your presentation.

    b. At the presentation, you will start by copying the folder which contains all your files to the instructor’s

    computer in the specified location (this will be demonstrated before presentations). After removing the

    USB drive, you will begin your presentation:

    i. Introduce yourself, your major, and the title of your design project. If it is something obscure,

    be prepared to describe it in a few short sentences.

    ii. Open your assembly file to show the isometric view of the entire assembly with shading. You

    may be asked to rotate your model.

    iii. Zoom in and comment on a part for each feature type;

    1. revolve,

    2. loft,

    3. sweep,

    4. 3D edit (shell, fillet, chamfer, etc…).

    NOTE: This does not have to be the same part.

    c. If time permits, you may also highlight any other features you are particularly proud of.

    Important

    1. You will be cut off at the 6 minute mark to allow the next student to present, so make sure you have shown all you need to show as described above within the time limit. It is strongly suggested you practice your

    presentation well before the deadline.

    2. There will be no extensions to the project deadlines. Any student who does not present his/her work to the class on the due date will receive a zero (0) for that project. If you’re having problems, see an instructor well before

    each deadline. Emergency situations will be handled as described in the ―Syllabus‖ handout.

    3. Lastly, not all projects are appropriate for this class. Some inadvisable projects: ; Buildings: The scale of a building tends to be quite large. Details tend to get lost and the computers start to

    have difficulty above a certain scale

    ; Bridges: See buildings

    ; High performance aircraft: These often employ very complex geometry which is generated with extrusion

    techniques beyond the scope of this class.

    ; Toolboxes: A toolbox is generally not enough parts. This inadequacy is often made up for by drawing the

    tools in the drawers. Tools aren’t actually part of the structure and therefore should not be included.

    ; Leatherman Tool: Although technically it meets the requirements, each of the components is only one or

    two extrusions. This will not result in a good grade.

    ; Rooms: See Toolboxes and Buildings

    ; Desks and their components: As with the toolbox the limited number of unique parts tends to be made up

    with by placing things on or in the desk.

    These projects are by no means prohibited. If a student can present a plan that shows any of these as a valid

    project then they may be allowed.

    Here is a small list of previously successful projects to assist those having difficulty deciding.

    ; Mechanical clock ; Motorcycle

    ; Hard drive ; Bicycle

    ; Sewing machine ; Lawnmower

    ; Printer or typewriter ; X-Wing or Tie Fighter

    ; DVD player or VCR (beta or VHS) ; Fishing Reel

    ; Fan (not a PC fan) ; Stapler

    ; Boat ; Machining shop equipment

    ; Certain aircraft ; ASME Moon buggy

     ; Spacecraft

     ; Engine (almost any type)

     ; Electric pencil sharpener

    This list is not comprehensive; plenty of other projects are possible.
