University of Oregon - Department of Architecture - ARCH 424/524 Cheng - Advanced Design Development Media
Objectives: To understand how structuring graphic data affects the ability to manipulate it; To understand specific data structuring tools.
| Review | Ambiguity | CAD organizers | Project Planning |
I. Web Authoring
II. Ambiguity, Structure and Interpretation
Organizing as intellectual analysis. See graphic examples.
III. Structures for organizing CAD data
- 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.
- 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
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.
