COMBINING/MORPHING BASIC SHAPES TO FORM PRODUCTS , ORTHOGRAPHIC VIEWS 5 Adding fillets to all edges of a cube: Draw a cube and fillet all 12 edges by drawing cylinders on all corners. Note that the filleted cube does not touch the original boundaries of the cube. However, in most cases it is possible to just round off all corners of the original cube and no one will ever notice the difference. Draw contour centerlines to further define the form.

Combining and morphing basic shapes to form products: Demo using rectilinear forms, spheres and cylinders to make a simple product, such as a calculator or pencil sharpener. Explain sky and ground reflections, contour centerlines.

Intro to spheres/half spheres and contour lines: A circle in perspective drawn on the side of an object can become a “bump” or a “dip” simply by using a curved contour line.

In class work: Design a simple product by using primary shapes that are stretched or distorted. Product can be from your prototypes class, or another product such as a cell phone, MP3 player, or pencil sharpener. The form should be simple, using rectilinear or cylindrical elements.

Intro to orthographic views and overall dimensions. Using the top, front and side views in combination with perspective views to communicate your design

ASSIGNMENT:

Warm-up exercises: 5 pages of ellipses on curved centerlines.

Continue designing your simple product-

Use black Prismacolor pencil on white 18 by 24 bond paper. Show contour section lines. Do 5 pages of designs, at least 5 designs/views per page. Fill each page with sketches. These are thinking sketches, not presentation drawings. (4-5 hours)

Choose ONE design that you like, and do three different presentation ROUGH LAYOUTS on 14 by 17 tracing paper, marker paper or newsprint (drawings on newsprint should not exceed 14 by 17). Each layout must show at least two perspective views plus one orthographic view showing overall dimensions. Title, background and call-outs of features should be indicated. One view should show a hand interacting with your product to show scale or use.

Focus on:  Page layout. One dominant view, plus supporting views to convey your idea clearly.  Balance the page with interesting views and backgrounds. Avoid symmetry.  Centerlines and contour lines to show form.  Sketch all views lightly on the page, shift views if necessary, then darken them in.
