Convert STL to 3DM

STL, short for Stereolithography, is a widely used file format in the realm of 3D printing and computer-aided design (CAD). Introduced by 3D Systems in 1987, it represents the surfaces of a 3D object through a collection of triangles, facilitating precise and efficient model creation. Utilized across various industries such as engineering, manufacturing, and healthcare, STL files are critical for prototyping and producing complex geometries. Their simplicity and compatibility with numerous software applications have cemented STL's importance in the digital fabrication landscape.

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.
