## 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:

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

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

Direct 3D Doghouse

• Extruded Mass, Hollowed
• Boolean Mass, Boolean Void
• Inserted Planes for Details

2D to 3D Doghouse

• Glass Plane Drawings as Guides
• 2D Plan, Extruded vertically

Another Doghouse

### VIII.  Context

Modeling methods & applications

Architectural

### 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)
