IFC or Industrial Foundation Classes is a 3D file format, used in the Architecture Engineering Construction (AEC) segment. It’s supported in the major software packages like Revit and AutoCAD by Autodesk, Tekla Structures by Tekla or SmartPlant3D by Intergraph. The main value of the IFC is accordance to the Building Information Modeling requirements. BIM is a concept of design, construction and exploitation of the buildings prescribing creation of the large volume of the digital data around architectural objects. This data may include not only 3D geometry, but tons of information pieces like authors, milestones and deadlines, supplier information and so on. Prior to beginning of the construction, the data base is created. It will include all the information, related to the building. Once the process kicks off the project team members will populate the data base with all the aspects of the future building.
PRC (Product Representation Compact) is a 3D file format that can be used to embed 3D data in a PDF file.
This highly compressed format facilitates the storage of different representations of a 3D model. For example, you can save only a visual representation that consists of polygons (a tessellation), or you can save the model's exact geometry (B-rep data). Varying levels of compression can be applied to the 3D CAD data when it is converted to the PRC format using Adobe Acrobat 3D.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
