TAD Docs

Taxonomy means classification system. SFA stands for Sabu Francis and Associates, the company that holds the copyrights to TAD.

The SFA Taxonomy is based on the fractal theories in geometry. According to this, all volumes found in any piece of architecture can be either represented by solids or spaces.

Objects in TAD are classified into the following kinds as per SFA Taxonomy:

• Atom - It represents the space inside a room.
• Envelope - It represents an enclosure wrapping an atom or a group of atoms.
• Connector - It represents elements that connect atoms to envelopes. For example, Doors and windows.
• Artefacts - It represents elements that cannot be further sub-divided at the current level of investigation. For example, Canopies, Interior furniture, etc.
• Linked-nodes - It represents a set of artefacts that are linked to each other. For example, Column-beam frame, etc.
• Pseudo objects - It represents the objects that are not actual built objects. For example, Referential objects like Lights, Location, Look at.

Note: In TAD, objects are assigned their properties via isKindOf option in the Site Info Pane.
