5 Challenge

Build a model of the metal spoon that has been distributed in class. Orthographic top and side view images of the spoon are provided for your convenience below.

Build the object shown below. The Rhino file available here has curves you can use as a reference to build with / from.

Working from the provided Rhino file, build the form shown below (do not use the patch tool!)

Orthographic Views:

Create several chair models, each one using the following commands as the primary (if not exclusive) method for creating the form:

1. Revolve
2. Extrude
3. loft
4. Sweep1
5. Sweep2
6. NetworkSrf

Put each model on a layer in the same Rhino file. Using Keyshot, create a rendering of the 5 chairs in one image. Post this image to the shared google drive. Name this file: FirstnameLastname_6Chairs.jpg

Using the Rhino file provided below as a starting point, build the object shown below, paying attention to the transition between surfaces.

Build a model of the toy boat indicated in the orthographic views below.

Download the PDF file below which will cover the steps to build the mustard bottle shown below.  If you get done with this early, see if you can use the images below to use as textures to create a realistic rendering of this object.

Build a model of a sharpened wood “golf” pencil. Sample pencils will be distributed for inspection and measurement. First and foremost this exercise is about form, but proportions and dimensions are important too. Don’t worry about materials you can build this as if it was all one single material / piece.

Using this Rhino File, assemble the Lego figure in the poses indicated this document.

Keep the original model, and make a new layer (or set of layers) for each pose.

Fit a control point curve in the tubes included in this model. Use the exact number of points indicated by the layer name.

Use the image below to trace the figures shown in red.  Each figure indicates the drawing tool you should use and two of them have specific instructions about the number of points your drawing should have.

Paper versions of some handouts will be distributed for your convenience.

1. Transforming Exercise
a. Follow the directions in the PDF called “TransformExercise”. Work in the Rhino file named “TransformExercises”, it contains all of the geometry you will need, with each problem on separate layers. Place your work on the corresponding layer as you go, as necessary.

2. Drawing Exercise
a. Trace the 3 objects shown in the Rhino file named “TracingExercise” using the polyline and control point curve tools.
b. Recreate the geometry indicated in the PDF called “PrecisionDrawing+RevolveExercise”.

3. Modeling Exercise
a. Recreate the revolved solid shown in problem 2b.
