What is a 3DM file?
3DM is the native file format of Rhinoceros (Rhino), a popular 3D modeling software widely used in architecture, industrial design, and jewelry. It is based on the open-source 3D graphics framework OpenNURBS and supports both NURBS and mesh geometry.
3DM files are known for their accuracy and flexibility and are compatible with many design applications through plugins and libraries. They are ideal for complex, mathematically precise 3D models.
How to open 3DM files
3DM files can be opened with Rhino 3D, as well as other CAD and modeling programs that support the OpenNURBS initiative. Applications like Blender and Autodesk Fusion 360 also support import via plugins.
Use AnyConv to convert 3DM to more universal formats like STL or OBJ for use in 3D printing or rendering software.

What is a STL file?
STL (Stereolithography) is one of the most common 3D file formats used for 3D printing. It describes the surface geometry of a 3D object without including color, texture, or other attributes.
STL files are supported by virtually all 3D printers and modeling software. They are lightweight and easy to process, making them the go-to choice for rapid prototyping and additive manufacturing.
How to open STL files
STL files can be opened in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, and Fusion 360. They are essential for 3D printing workflows.
Use AnyConv to convert STL files to formats like OBJ or STEP for further editing or integration with CAD systems.
