I. Review of Student Work

II. Constructing CAD (originally in lesson 8)

• Example of hierarchical modeling.
• Example of solid modeling: Frank Lloyd Wright concrete block study

1. opening eiffel.fmz from Session Nine of the Course Disk
2. extruding a closed A-shape to make a long bar
3. subtracting a void
4. rotating the bar 90 degrees
5. intersecting the two.

III. Designing with CAD

• Parametric variations or adjusting lengths, quantities, angles (parameters) to adjust proportion, balance, hierarchy of parts.
• Geometric transformations
• Substitution of alternate symbols can help refine a design by adjustment of parts.

• Different viewpoints exposing particular aspects
  
  Switching between god-like axonometric and naturalistic walk-throughs

  Isolating or juxtaposing separate building systems for examination

  Providing feedback on performance (i.e. quantity of materials, structural, HVAC, acoustics, lighting) See example of a bus terminal bay.

C. Increasing the chance of re-reading ambiguity can lead us to new directions.

• Work in 2D to increase fluidity: draw in 2D CAD or use Photoshop to sketch on renderings
• Change media:
  Sketch over hardcopy
  Use the CAD file to generate templates for a physical model

  Introduce serendipity or chance juxtaposition into the process.

  Get a partner to exchange projects for an hour to get a fresh outlook.

D. Take advantage of advanced 3D CAD transformations such as these in FormZ (tutorial #)

• Extending faces to join one another (19.8)
• Inserting holes, openings, faces or solids (21.2)
• Deforming 3D objects (13.3)
• Trimming and Stitching meshes (16.5)
