Windchill Database Relationships - CAD Document Parameters

Here is a picture (and corresponding PDF) showing the mapping between EPMDocuments (CAD Documents) and their version specific attributes (parameters).  There is also a sample SQL query that will return all Boolean values for each CAD object by version.  Hopefully this will help others out who are trying to understand the database relationships.

I'm sure PTC already has this documented somewhere in some 1000+ page guide, but hopefully this is a little more accessible.
