Session Seven

I. Web Authoring

II. Ambiguity, Structure and Interpretation

Organizing as intellectual analysis. See graphic examples.

III. Structures for organizing CAD data

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.

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. Tutorial on Groups & Symbols

V. Tutorial 4.2 on Symbols

VI. Project Planning

• 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 3 to plan basic modeling elements and how they go together.
