IET 265.001
Three-Dimensional Modeling 
(Using SolidWorks)
Spring Quarter 2008
 

Class Website

Final grades are posted at the link below.  The grade breakdown for the Final Project can be found  by clicking on the tab named "Final" on the bottom of the Excel document.

This was an excellent class and I anticipate that all of you have gained a good deal of knowledge of design using SolidWorks and will apply what you have learned in your careers ahead.  SolidWorks is constantly innovating so make certain that you keep up with it in the years to come.

As a whole the Final Projects were excellent with many putting in the extra effort.

Some projects that I thought displayed extra design features (that I was able to get an image of) are included in the Design Gallery link below. 

Good Luck and send me an occasional email.  CSS

Drawing Guidance:

The following are tips on getting a decent grade on your drawings for your design assignments.

  • The premise here is to make your drawings as neat and as readable as possible eliminating errors and ambiguity. 
    • Remember, in the real world, mistakes and ambiguity cost time and money.
      • In this class these mistakes will impact your grade.
    • Always present your best work, fix your own mistakes!
      • Double check your work before giving it to others. 
        • Check it on screen first
          • If any errors are found correct them before printing
        • Check the printed copy second
          • If any errors are found make the corrections then reprint.
      • If I find these mistakes and mark up your work it will affect your grade.
Generalized Grading Criteria:

The list below may be modified as the quarter progresses:

    Appearance:
    • Center your drawing views in the drawing area so that it fills the page without over crowding or leaving excess space.
      • Try to provide equal spacing between your drawing views and the top and bottom of the page as well as from the left and right
        • This includes drawn objects as well as notes and dimensions.
        • The spacing between the drawing views and the border of the drawing should be about half of the spacing between each of the drawings views in the field of the drawing.
    • Dimension your drawing views according to conventional standards
      • Move dimensions around to avoid "crowding"
      • Include the word "TYPICAL" following dimensions that can apply to similar items in the same view such as a series of holes, fillets or row and column offsets.
      • The isometric view should have no dimensions in it. 
    • Properly fill in your title block, with CAPITALS only.
    • Provide an appropriate sheet scale (a scale that applies to every view in your drawing):
      • Use standard scales such as
        • Metric: 1:1, 1:2, 1:5, 1:10 and similar multiples.
        • SAE: 1:1, 1:2 (6" = 1'-0"), 1:4 (3" = 1'-0"), 1:6 (2" = 1'-0"), 1:8 (1-1/2" = 1'-0"), 1:12 (1" = 1'-0"), 1:16 (3/4" = 1'-0") and similar multiples of 2,4 and 8.
        • Automatic scales added such as 1:3, 1:7. 1.5:1 and other non traditional scales need to be modified to standard scales.
      • Label each view with its own scale if it is different from the sheet scale.
      • The isometric view should have no scale label on it.
    • Provide a proper View Title, in CAPITALS with UNDERLINED TEXT.
      • Position the View Title centered under the drawing view.
      • The View Title should have the following information answered in the following order top to bottom, what is it? what view is it? what scale is it (if different from the sheet scale)? and any note references that apply to that view. 
      • Label each view with its own scale if it is different from the sheet scale.
    Avoid duplicate information, this leads to ambiguity.

  • On "B" sized sheet landscape
  • Scale 2:1
  • Show hidden lines in the front, side and top views
Consider the images below as a guide for this week's drawings

The following is how your Title Block should look for the drawings due this week.  Make any additions and corrections necessary as shown below.  Make sure you make these corrections to your template files. 

To change the units go to "sheet format" right click on the text block, choose "Properties" and make your text changes. Your "Name" (company name), "Initials" (drawn by), and "Date" (drawn date (use a current date)) are set by selecting the "Properties" option from the "File" pull down menu, choosing the "Custom" tab and selecting and filling out the appropriate entry.  The "Part Description" is imported from your part or assembly being inserted into your drawing.  The sheet scale is set when you import a part or assembly and will change when this is modified on the sheet.  The drawing file name is what you name the drawing file.  All the text in your drawing should be CAPITALS excepting the drawing file name.

    To do this week: 1 item.
    • Final Project drawings
      • Basic (not final) parts and assembly drawings, images or models depending on what is required per your abstract reply from Week 8.

    Details on the design portion of Examination No. 2 follow below. 
    These items can be accomplished before and used for the exam. 

    Create the following, building on your design from Examination No. 1

    You will create three additional components the 
    Barrow, Back Leg and the Handle.

    The Barrow will be a Loft Feature with sketches drawn on two planes with sketch fillets.  The top sketch will be on the Top Plane with the bottom sketch on a plane 8 inches below the Top Plane at the back and inverted at a 8 degree angle.  After the loft there will be a shell feature selecting the top face at 0.20" thick.  Add texture using Brushed Metal 4.  Use a texture scale at the bottom.


     The Back Leg will be a sweep feature as shown.  The bolt holes will be 
    10" apart.  Color will be dark gray.


    The handle will be your own design.  Standard credit for a no frills design.  Extra credit for finger grooves, ribs and other features.  Material is rubber.

    Extra credit will be offered on extra details added to any feature as long as it adds to either the form or function of the overall design.  Examples include, but are not limited to, treads on the tire, axle caps with flourishes (think, Ben Hur and the chariot race scene), fenders, head lights, a brace connecting the Back Legs, a pour spout on the front of the Barrow, streamers and hand guards on the handle.

    Modifications to the Examination No. 1 parts include a new hole 10 inches behind the last hole in the Side Mount to allow for the attachment of the Back Leg.

    The Wheel Mount will now be two different parts, Wheel Mount Left and Wheel Mount Right.  Prior to the exam, delete the holes in the Wheel Mount before making a copy and renaming them.  Both of these will be modified "in context" with the assembly during the exam.

    We will create a new assembly and name it "Wheel Barrow".  Make certain that all of your parts from Examination No. 1 have been corrected, see your markups from the last exam.  Insert the axle (built with the profile on the right plane) "fixed" to the origin in the new assembly.  Next, add the Wheel Assembly as a sub-assembly.  With the center hole, provide a concentric relation to the axle and with the right plane of the sub-assembly a coincident relation with the right plane of the assembly. Add the Front Connector and the Side Mounts without any relations with the Axle and the Wheel Assembly sub-assembly yet (we will finish this during the exam).  Mate the right plane of the Front Connector  to the right plane of the assembly.  Mate the Side Mounts to the Front Connector like we did for Examination No. 1.  AThe bears in the back ground seem rather content.  I donít understand the behavior, but If bears are like dogs, smelling the rear end of your own kind is a pursuit my dogs certainly enjoy.   the Wheel Mounts to the Side Connectors with the left one on on the left side when facing the front while holding the handles.

    Details on the drawing portion of this design will be available during the exam.
     
     
    Finish your Final Project parts and assemblies this week and hand in your final parts and assembly drawings in the box.

     

    Final Project Presentation Procedures:

    In the CAD lab, on the day and at the time allotted for the final:

    Please copy a folder, with your name in the title, of your project onto the instructor's computer on my "desktop" into a folder named 080604-Final Project.  Come early if you can, however, there is a class final preceding ours and we must be respectful of their time.  Please leave your folder on the desktop when you are done with the presentation so that I can grade the parts and assembly portion of your project. 

    Our presentations may run a little past the time allotted.  Please prepare for that and let me know if you have other time conflicts with this.

    I will have a presentation schedule posted on the website Tuesday evening. 

    The grade sheet has been updated along with a tab named "Final" containing a grading template for the presentation portion of your Final Project.
