Documents and doc objects

A Document is the unit of loading and saving. Assuming it has been saved, a document corresponds to a Discovery scdoc file on disk.

A DocObject is an object that belongs to a document. Doc objects aren't the only objects that get saved when the document is saved, but they are the only objects that have a Document property. Examples of doc objects include: Part, Component, DesignBody, DesignFace, DatumPlane, and Note.

Doc objects provide:

• A parent-child tree containment hierarchy.
• Monikers for persistent identification.
• Update states to indicate that the doc object has changed.
• Custom attributes for storing third party data.
