4 Modeling
Objectives:
- To understand the operational logic of a 3D modeling application
- To see how modeling is used for architectural applications
I. Updates to the course website
- Announcements
- Gallery
- Resource note: Computing Center Documents Room
- Listserv
II. Web Authoring
Photoshop Slices, GoLive Components, Stationery
III. Modeling: Revit & FormZ
Interface:
Help menu, Modeling tools
Simplifying the menu
Tile Windows
View menu > Edit Cone of Vision
IV. 2D shape to 3D form
Extrusion
Lathing
Lofting
A. Derivative Objects
TUT 7.3* from parts of other objects, TUT 7.5 Parallel objects
B. Protrusions
TRY IT: Simple roof forms
C. Lathed objects
TUT 8.1
D. Sweeps
Axial 2 source TUT 9.2 2 path TUT 9.3
V. Precision Tools
- Grid Snap
- Angle Snap
- Object Snaps
Absolute vs. Relative coordinates
Query operations
VI Basic Transformations
D'Arcy Thompson's On Growth and Form
1 2 
3
Basic Operations:
- Translation
- Reflection
- Rotation
- Scale
- Glide reflection (Translation + Reflection)
Order of operations DO matter
Selection set DOES matter
VII. Ways to model
- Extruded Mass, Hollowed
- Boolean Mass, Boolean Void
- Inserted Planes for Details
- Glass Plane Drawings as Guides
- 2D Plan, Extruded vertically
- Gingerbread House
VIII. Context
Modeling methods & applications
Teddy: sketch interface for polygonal modeler
Alice animation: programming objects
Sharper Image:3D objects in Web Commerce
Architectural
3D Scanning
Construction via animation (UVA, Stanford CIFE 4D-CAD)
Historical database (Palladian Villas at MIT)
Urban models for planning (Bath, LA)
Visualizations (Kent Larsen's Unbuilt Kahn)
Design: ACADIA Library Competition
IX. Vocabulary
- Selection Set (elements chosen for editing)
- Attribute (characteristic)
- Relative Coordinates (distance from another location)
- Absolute Coordinates (according to world origin)
- Geometric Transformation (change of location, size, proportion, orientation)
- Parametric Variation (alternate created by changing size, angle or number)
- Topological Levels (point, segment, face, object, etc.)
- Derivative Object (a form that is created from an other)
