DAE is an interactive 3D file format used for exchanging digital assets between various 3D modeling systems and game engines.
The DAE format was created using COLLADA XML architecture, which is an open standard for transmitting digital assets between graphic applications, and now owned and developed by Khronos Group.
The following software can be used to view, alter, and process DAE: Bentley Systems MicroStation, Autodesk AutoCAD, Autodesk 3ds Max with the ColladaMax plugin, and Autodesk Maya with the ColladaMaya plugin.
A PRT format is used to store components of 3D CAD models. It may contain lines, surfaces, textures, dimensions, and metadata.
The .prt extension is mostly associated with the Siemens NX Part (PRT) file type as an acronym for "part". PRT files may be exported to various standard CAD and 3D modeling formats (e.g. OBJ and STL) in addition to being utilized natively in Siemens NX.
The PRT file is also a part created by PTC Creo Parametric 3D software. In PTC Creo, project part files can be combined in a single assembly file with an ASM extension.
Despite the same extension name different CAD software produce PRT files differently, i.e. PRT files produced with Creo are not the same as PRT files generated from NX.
The PRT extension is also compatible with Dassault Systèmes SOLIDWORKS.
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.
