I. Organizing structures

• Layers allow division of graphic data into categories.
• Object hierarchies allow structured grouping of data within these layers.
• Symbols save the definition of repeatable elements which can be identically instanced or exploded and customized.

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)

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.
