Assignment 7
Sculpted Forms

Due at the end of our ‘Lecture’ meeting in Week 5

Concept Sketch:

Sketch the design of a part or assembly that includes some sculpted form. Sketch freehand on plain 8 x 11 paper using any combination of orthographic or isometric views. Include a title at the top, some reference to size, material, how it will work and how it will be made. Include your name, signature and the date.

Artist’s Rendering:

Take a crack at drawing what the design would look like in its environment. Try to avoid abstraction by use of tone (shading) in place of line. Include shadows. Use pencil on plain 8 x 11 paper.

Manufacturing Plan:

Consult with Mr. Johnson to develop a plan for how each part will be made. Use Microsoft Word (.doc or .htm) to detail how each part will be made and what design restrictions apply based on process capabilities (shapes, finishes and tolerances, etc).

Working Drawings:

Use Autodesk Inventor to produce a complete set of working drawings (parts and assemblies as necessary) for your design. Include all views necessary for clarity (consider isometric). Fully dimension* and tolerance, but do not over dimension (reference dimensions are welcome). Also, demonstrate some geometric tolerancing and surface finish control. Use A-size sheets, standard title block and border, and add all pertinent notes (don’t forget visual inspection if applicable). Plot all drawings 1:1.

*presuming that there’s a sculpted form somewhere in your design, that portion will not be dimensionable. Instead, use a leader to reference your computer model by name and location (see Fig 6.8). Dimension all dimensionable geometry.

Computer Rendering:

Use Autodesk Inventor to produce a rendered image of your design. You are welcome but not required to present the design in its environment.

Advice:

1.      Keep it simple!

2.      A spline revolved about an axis produces a quick sculpted part.
