The Open Design Alliance (ODA), a non-profit consortium of over 2,000 software developers and users committed to promoting open, industry-standard formats for the exchange of CAD data and CAD legacy data, works with third party component vendors to deliver direct access to a variety of additional features to members.
The list of third party components available to ODA members (ACIS from Spatial, HOOPS from TechSoft3D, Adobe-Based PDF) has been extended with the Constraints Support from LEDAS.

A sample application demonstrating a number of constraint-related features can be found on the ODA web site. The demo implements the following functions:
