                                          Title
                                  CD Holder Challenge

                                    The Situation
The Mr. Principals desk has been getting more and more cluttered as the school year has
progressed. Detention slips, tardy slips, and absent excuses keep piling up with no end in
                                           sight.

                                    The Problem

  With all of the paper piling up, Mr. Principal is having a very hard time keeping his
collection of Vanilla Ice CD’s organized. He is spending too much of his valuable time
           searching for his favorite CD’s under the mountains of paperwork.

                                   The Challenge

      Design a desktop CD holder for Mr. Principal to organize his CD collection.

                                     Constraints
                           The CD holder must hold 10 CD’s
 The CD holder must fit into an area that is 10 inches wide, 10 inches high, and 7 inches
                                           deep.

                                        Task #1
Using Isometric grid paper, make an Isometric sketch of your CD holder design. Include
                        all dimensions and any important notes.




                                       Task #2

Use Pro Desktop design software and the information from the Isometric sketch to make
 a 3-D model of your design. You must use at least 3 different features. Use album to
   render your design to show the material that will be used to construct your design.
            The following features may be useful to complete your design:
                                       Project
                                       Extrude
                                      Duplicate
                                        Round

                                 Task #3 (Optional)

        Use materials available to you and construct a prototype of your design.
                                   Possible materials:
             Styrofoam                                       Modeling Clay
             Cardboard                                            Paper
             Sheet metal                                          Glue
              Plexiglas                                           Tape
               Wood

                                      Grading
                 Each Task will be graded with the following Rubrics.
