Standard for the Exchange of Product Model (.stp)

The STP file extension stands for "Standard for the Exchange of Product Model" (STEP) and is used for 3D CAD files. Developed by the ISO in 1984, this format facilitates the exchange of digital models between different CAD systems, enhancing interoperability and collaboration in engineering and manufacturing. STP files store 3D object data in a text format that includes geometric and functional product information, supporting various stages of Product Lifecycle Management (PLM). They are widely adopted in industries such as automotive, aerospace, and industrial design for sharing complex 3D models.

Rhino 3D Model (.3dm)

The 3DM file extension, standing for "3D Model", is associated with the openNURBS initiative, which facilitates the exchange of 3D geometry across CAD, CAM, CAE, and computer graphics software. Developed by Robert McNeel & Associates, it serves as the native format for Rhinoceros (Rhino) software. Introduced to address interoperability challenges, 3DM files store precise 3D models using NURBS (Non-Uniform Rational B-Splines) and polygon mesh representations. This format is widely adopted due to its open-source nature, enabling developers to read and write 3DM files without proprietary restrictions, thus promoting seamless data sharing in 3D modeling workflows.
