Collada (COLLAborative Design Activity) is an interchange format for interactive 3D applications. Originally developed by Sony Computer Industry, now it is managed by the Khronos Group, a member-funded industry consortium, which now shares the copyright with Sony, Recently Collada has been well adopted by ISO as a publicly available specification, ISO/PAS 17506.
It is an XML-based schema that allows data exchange among 3D Digital Content Creation tools, such as SketchUp, Maya, 3ds Max, and Rhino. COLLADA files have the *.dae file extension, which stands for digital asset exchange.
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.
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
