Updated Conversion Process and Data model

To address the problems with CAD Conversion due to locked CAD Items, the conversion process, CAD data model, CAD Form, and 3D viewing logic were updated^[1]. These updates included the following changes to the data model:

The Viewable, Thumbnail, and Monolithic Files are now stored using File Relationships similar to the View and Assembly XML Files. The logic for saving these files exists within the added conversion logic and also with the CAD Item itself as part of the 3D Visualization Platform Component. As a result, storing thumbnail, PDF, or PRC files directly on the CAD Item when using 3D Visualization (through manual or automated processes) will result in the generation of File Representation relationships so that the data associated with the CAD Item is consistent. The dynamic and streaming_enabled Properties are no longer updated and will be disabled in the CAD Form. The bounding box Properties (i.e., x_min, x_max, y_min, etc.) are now stored in a new Null Relationship – CAD ConversionInfo.
