A ControlDraw model is an Access database. ControlDraw2 models are Access 97, CD3 uses Access2000, but can still edit CD2 (Access 97) Models.
The model is populated with records automatically as you draw diagrams, and then can then be enriched with further data with a few clicks in the the Database forms, and of course some data entry.
This contains the diagrams, the matrices and everything else.
The Instances table records all of the occurrences of a particular Generic Symbol.
This procreates the parent_child relationships in a drawing file to produce a record for all of the
Parent children paths. The Instances table provides the interface to the real world of instrumentation and
operators and system testing. For example you can generate lists of all of the points in a system as a test schedule.
