Fall 2006 Final Exam—Part II: "The Brewzer"

For your final exam, you will need to generate a 3D model of an exciting new development in bar room technology: "The Brewzer".
Beer Knuckler
Based upon the design parameters provided in the senario described below, use AutoCAD and Rhino 3D to complete the assignment.

You are the victim of your company’s marketing department, bad timing, and your own alleged competence. Yes, that’s right. Once again, the president of the company has promised a new customer (with very deep and cash-filled pockets) that he has developed a new style of drinking mug.

The problem? He conveniently forgot to tell his normal stable of designers about it this morning before they all went off on some sort of New Age, feel good, team-building, rock climbing outing (and they are out of cell phone range, drat it all). Oh yeah, the client is dropping by to see this really cool new mug design in about two (2) hours. And because of your CAD skills, you are the only soul in the office that can pull his over-committed tail out of another fire and be the hero.

If you want to keep your job—you know, the one that allows you to support your loving spouse/life partner in the manner to which he/she has quickly become accustomed—then you need to develop a quick & dirty 3D model of this new style mug based upon the following specifications:

Mug body specifications:

  • Outside Diameter = 3.25" (corner to corner) with 10 equal facets (flat surfaces)
  • Overall Height 5.25"
  • Inside Diameter = 2-5/8" (cylindrical)
  • Inside Depth = 4.00" (from top)
  • Bottom "truncated cone": 2-1/2" ID opening (at bottom)
  • 3/4" deep (from bottom)
  • 1-1/2" dia. flat at top

Handle specifications:

  • Finger holes: 4
  • Nominal hole diameter: 7/8"
  • Finger hole Ctr to Ctr distance: 1"
  • Outside wall thickness: .25" minimum
  • Handle thickness = 0.25"
  • You may download and use a prototype Rhino 3D handle design, if desired. Feel free to modify the file as desired.

When you have completed the assignment, emboss the mug with your name and save your work on your PC's local hard drive for instructor check-off:
  • the 2D AutoCAD file (if used)
  • the DXF file (if used)
  • the Rhino 3DM file (saved small)
  • a colored rendering of at least one mug saved in JPG or BMPformat
