Vectorworks Vectorworks is a computer-aided design (CAD) and Building Information Modeling (BIM) software program developed by Nemetschek Vectorworks that is used for drafting, technical drawing and 3D modeling. Vectorworks offers 2D, 3D, production management, and presentation capabilities for all phases of the design process. Vectorworks exports to various 3D file formats with varying degrees of integrity. There are several "best conversion" methods from Vectorworks which will retain the geometry, part naming, assembly hierarchy, materials and texture map associations. Based on real tests of complex Vectorworks models, you can export the model from Vectorworks using the Cinema-4D .c4d, COLLADA .dae, FilmBox .fbx and/or DWF-3D .dwf file formats. Please make sure to choose the correct Vectorworks export radio button option to retain the class structure (so that the part naming and assembly hierarchy is exported). |

Universal Scene Description The USD format (“Universal Scene Description”) is an open 3D model and scene format designed for efficient storage and streaming of 3D asset data. It is a high-performance extensible framework and ecosystem for describing, composing, simulating, and collaboratively navigating and constructing 3D scenes. An extensive overview of USD is provided in the Okino USD documentation. Pixar Animation Studios originally created the USD platform (as its fourth generation variation after its Marionette & Preso systems) to improve studio-wide collaborative workflows. USD provides a concept of "scene composition", building a unified scene from potentially thousands of loosely-coupled source assets. For example, the mesh, rigging, materials, and animation for a single model might all come from different "layers" (files), each created and maintained by a different artist or department. Layers can store multiple "variants" of any given data, helping to solve problems of versioning/approval. The coupling between layers is very dynamic and loose, allowing for greater flexibility during the production process. The entire USD system is designed to facilitate a large studio making feature films, with all of the scale that that implies. USD should be considered more of a code framework (“OpenUSD”) for use in group collaboration, to help with the aggregation of various 3D data sources into a unified scene through a process referred to as scene composition. A subset of that code framework provides for reading and writing USD disk-based files as well as rendering USD scenes (Hydra). The system is rather complex to implement (for software developers) and to use (from first principles) as a 3D graphics artist. The USD file format itself is not for faint of heart and is best read/written using the OpenUSD SDK + various programming APIs. More commonly used ASCII 3D file formats such as COLLADA, VRML2 and Wavefront OBJ are much easier to manipulate/understand/use on a human level basis. File extensions used by the standard include:
