According to the AGC Contractor’s Guide to BIM, a 2D conversion is:

A 2D Conversion is the process of taking the TRADITIONAL CAD files (such as .dwg) and using the attributes NECESSARY to ADD the third dimension that allows the 2D design to begin taking its 3D form.

The Contractor’s Guide’s definition simplifies the process somewhat; a 2D conversion is not a process that occurs automatically with the click of a “2D Convert” button. A 2D conversion requires that a modeler digitally trace the 2D DOCUMENTS in an object-based modeling program.
