4 Modeling


  • To understand the operational logic of a 3D modeling application
  • To see how modeling is used for architectural applications

I. Announcements

  • Course References
  • Resource note: Computing Center Documents Roo

II. Review of Student Progress

III. Designing in 3D

Design direction depends on interpretation

  • Design Process:  
  • Cycle of Think, Make, Look
  • Step wise refinement: Generate options, examine and select one, refine parts
  • Creating design alternatives:  practice improves agility

Formal Operations:

Parametric Objects (control handles) vs. Plain


A. Derivative Objects

TUT 7.3* from parts of other objects, TUT 7.5 Parallel objects

B. Protrusions

TRY IT: Simple roof forms

VI.  Setup & Control

Project Units

Precision Tools

  • Grid Snap
  • Angle Snap
  • Object Snaps
  • Coordinate Grid

Absolute vs. Relative coordinates
Query operations

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
  • Gingerbread House

VII. 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)
