Session Seven

Modeling III
Jan 28, 1996

Objectives: To understand how structuring graphic data affects the ability to manipulate it; To understand specific data structuring tools.

I. Review of Student Diagrams

(9:30-9:45)

II. Ambiguity, Structure and Interpretation

(9:50-9:55)

Organizing as intellectual analysis. See graphic examples.

III. Structures for organizing CAD data

(9:55-10:10)

A. Layers

Layers by material for rendering
Layers by building system (HVAC, Windows, Doors, Foundations)
AIA Layer standards (AR-WALL, AR-CONC)
Layers by system with components (Win-glass, Win-steel, Win-skylite)

Attributes of visible/ghosted/off, locked, snappable are in palette. Use layers for systems and subsystems which have similar attributes, use objects for specific grouping of parts with different attributes within these systems.

TRY IT: Layering exercise

B. Object & Group Hierarchies

From the Palettes menu, choose Objects.
Objects grouped and groups can be nested to allow control in editing.
Objects allow linking of parts for manipulation
Attributes of visible/ghosted/off, locked, snappable are in palette, similar to layers.

C. Symbols

Redefinable symbols parallel the use of redefinable architectural types. Repeated objects can be defined once and the placed as instances or identical copies.
Most programs allow insertion of non-typical stretched objects and the editing of placed copies which lose their identity.
Redefinition allows quick modification of design qualities.

IV. Workshop on Symbol Definition & Redefinition

(10:10-10:40)

V. Project Planning

(10:45-10:50)

Gather information, drawings to scale, photographs
Write down your thoughts, objectives of the project
Reduce the scope to something doable that has NOT been done
Use Assignment 4 to plan basic modeling elements and how they go together.
