Abstract
In one embodiment, techniques are provided for converting a CAD description maintained in a first storage format (e.g., a file-based storage format) of a source repository to a second storage format (e.g., a relational database-based storage format) of an output repository. The techniques may, generate a single, coherent representation from spatially ambiguous “fragments” by generating an acyclic model graph for each graphical view, and then storing models of the acyclic model graph in the second storage format (e.g., the relational database-based storage format). The techniques may further produce a post-conversion CAD description that preserves human-readable names and information relationships related to levels by examining attachment specific copies of level structures (i.e. levels and attached levels) referenced from attachments, and generating from these categories and subcategories in the second storage format (e.g., the relational database-based storage format).
