Week 1:

Read the introductory sections of both textbooks.  Also read and model Lessons 1&2 in the SG textbook and read and model Project 1 in the ED textbook up to page 1-64. 


 
 

 
Week 2:

An evaluation of 2 of the 4 models that we have modeled so far will be on Tuesday.  Refer to the guidelines below and the Grade Sheet link above and click on the Week 2 tab for the grading criteria.

Call me if you have any troubles, do not come to class unprepared!

Assignments include: The Guide, Axle, Shaft Collar and Flat Bars in the ED book. Tutor1 and the Door in the SG book.
See below.

For Tuesday we will have an evaluation of 2 of the 4 models that we have modeled so far.  The first one will be the Plate with the other either the Receptacle Plate or Switch Plate.  The evaluation criteria will include:

  • Completeness, models are finished with all of the features shown in the examples or in class. (5 points with 1/2 point off for each missing feature).
  • Dimensions, I will be looking for proper dimensions on your sketches (2 points with 1/2 point off for each missing dimension).
  • Fully Defined, your model sketches will be fully defined (lines are black) (1 point with 1/2 point off for each under defined line).
  • Feature Names, rename features to better describe what that feature does (1 point with 1/2 point off for each unnamed feature).  See example below.
  • Origin, the origin will have to be somewhere placed specifically in the model either in the center of your object or where the examples in the book show it to be located (1 point).
  • Extra credit, 1/2 point for each fully defined feature or element. 


Assignments: 
Complete the Guide, Axle, Shaft Collar and four configurations of the Flat Bars  (3, 5, 7 and 9) in the ED book.  A demonstration on configurations will be held in class.

Complete Tutor1 and the Door in the SG book.

Model a door, any door you like, in a manner you see fit with at least one door panel feature.  A demonstration on the Sweep Cut feature, which may be used to cut door panels, will be shown in class.
Information on the construction of a door follows in the images below, my door was 1-3/8" thick:







 
 
Week 3:

Assignments this week include 5 assemblies to graded in class next Tuesday.  Check the class schedule for details.

A few students were modeling the Rod from Project 1 in the ED book.  This model is available for download on the Student Resource page for use in Project 2.


 
 
 
 

 
Week 4:

We will cover Drawings this week.  As demonstrated on the first day of class SolidWorks provides a comprehensive way to demonstrate your designs in a 2D format (drawings on paper).  The first task on Thursday will be to update our new drawing templates using the Tutor2 drawing that we did in class on Tuesday.  Use these updated templates for the drawings due this week and for the rest of the quarter.  For the assignments this week, follow the Class Schedule.  Start with the SG assignments first then the ED assignments. 

All of the drawing assignments will be due on Friday of Week 5 by 5pm in the "box".


 
 

 
Week 5:

Your first examination will be on Tuesday, including both a written examination as well as a modeling exercise including parts and an assembly.  See details below.

Drawings will be due in the "box" by Friday of this week (in lieu of the usual Tuesday deadline).  They will be graded over the weekend and returned on Monday.  Check the "Drawing Guidance" section in the Student Resource section of the website for grading information.

The grades for your first examination will be posted this weekend as well as your drawing assignments due on Friday.  A letter grade for the quarter will also be assigned giving you an opportunity to see where you stand in class if I had to grade you as of this week.  I will be doing this every week now until the end of the quarter.

Examination Details:

In the 2 examinations for this class you will be modeling the parts and putting them together in the assembly of a Low Profile Garden Cart similar to the one in the image below:

For the first examination on Tuesday you will model the following parts and then put them into an assembly named Low Profile Cart:

For the modeling portion of the examination you will utilize the following design elements including:
  • 2 part Configurations on the Base Frame
  • Tool Box nuts, washers and bolts in the assembly
  • 2 display states in the assembly, one green and the other a color plus other attributes of your choice.
Some of the parts will be modeled before class on Tuesday with information supplied in class or described below.

The evaluation for the modeling portion of this exam will consist of the following:

  • Evaluation of your assembly similar to what we have been doing in class.
    • Include the 2 display states mentioned above
    • Fully defined 
  • Evaluation of a part similar to what we have been doing in class.
    • Include a part modification
  • A Part Drawing of the Base Frame (Bottom Frame configuration), to be printed by 7:30pm on Tuesday.
      • Include all of the elements shown in class for the Tutor2 drawing and in the templates that we worked on.
The Angle Support, model the following part:
  • Material: 1023 Carbon Steel Sheet (SS)
  • Sketch on the Right Plane in inches
  • Mid Plane Extrude to 23 inches
  • Hint, draw 2 rectangles and use the Trim sketch tool

Evaluation of the your Motion Study.

Those that missed the evaluation of your exam design assignment (the Low Profile Cart assembly and the Wheel Support part) during the examination will have only one additional opportunity for grading on Tuesday, May 4 during class.  I will not be taking  any points off since extra credit had been applied to those students who got their assignments done by the end of the exam.

Nothing is due on Tuesday.  We will go over in class on Tuesday the Candle Stick and Mug design assignments.  On Thursday we will cover the Threaded Fastener assignment and the Motion Study
