What is a 3DX file?
A 3DX file is a 3D model created by McNeel Rhino, a computer-aided design (CAD) program used for modeling complex surfaces and shapes. It stores 3D geometry data, including object structure, surface details, and modeling data. 3DX files are valuable for prototyping, rendering, and manufacturing workflows in various professional design fields.
More Information
Robert McNeel & Associates develops Rhino, which is widely used by professionals in architecture, industrial design, engineering, jewelry design, and 3D animation. The 3DX format allows users to save, share, and edit 3D models within Rhino.
Additionally, the format uses Non-Uniform Rational B-Splines (NURBS), a mathematical model that allows for precise curves and surfaces. Unlike polygon-based models, which approximate shapes using flat surfaces, NURBS enables the creation of highly detailed and complex surfaces using control points, weights, and mathematical equations, ensuring that curves and surfaces remain fluid and accurate, even when zoomed in or converted to other formats, such as .STL (for 3D printing) or .IGES (for CAD software interoperability).
NOTE: McNeel Rhino was previously known as Rhinoceros (Rhino) 3D.
