For very large assembly having hundreds of parts and thousands of features, you need a tool which captures geometry automatically from history tree of the assembly. Further, since the models get updated frequently, the synchronization should be made easy.
CADEC+ automatically captures entire feature tree of assembly and puts it in a database. Users can navigate to the required feature / parameter for linking. Further, you can auto-synchronize complete master model changes, selectively capture model history, capture feature either from model tree or 3D CAD platforms graphics window.
