PTC CAD Document Management domain provides access to the CAD data management capabilities of Windchill. CAD data management uses business objects, referred to as CAD documents to contain and manage CAD information in a Windchill database. A CAD document is a revision-controlled and lifecycle-managed object containing a CAD model or drawing file. The CAD model can be a file or a set of files containing information in a CAD application format. This domain enables you to get all the information related to a CAD document.
The following table lists the significant OData entities available in the PTC CAD Document Management domain.
