A 3DM file is a widely used file format in the field of computer-aided design (CAD) and 3D modeling. It is primarily associated with Rhinoceros, a popular software used for creating complex 3D models and designs. The 3DM format serves as a container for storing various elements of a 3D model, including geometry, textures, lighting, and other related data. This versatile file format is known for its ability to represent both simple and intricate designs, making it a favored choice among architects, engineers, and designers across various industries.

Within a 3DM file, the geometry information is typically stored in the form of NURBS (Non-Uniform Rational B-Splines) curves and surfaces, which allow for smooth and precise representations of complex shapes. These NURBS-based models offer a high degree of flexibility, enabling users to perform modifications and manipulations with ease. Additionally, 3DM files can include metadata such as layer information, object properties, and assembly structures, making them well-suited for organizing and managing large-scale projects.

One of the major advantages of the 3DM format is its compatibility with a wide range of 3D modeling software. While it is primarily associated with Rhinoceros, many other CAD applications and 3D design tools support importing and exporting 3DM files. This facilitates seamless collaboration between designers and various stakeholders, allowing them to work on the same project using different software. The widespread use of 3DM files in the design industry underscores their significance as a reliable and efficient means of exchanging intricate 3D models.

Our 3DM 3D Model/Mesh tool does not support any color material data contained within 3DM files so the converted file will not contain any color information.

An OBJ file is a widely used file format in 3D computer graphics that serves as a standard representation for 3D models. It stands for "Object" and was originally developed by Wavefront Technologies. OBJ files store geometric data, such as vertex positions, normals, texture coordinates, and face information, describing the surface of a 3D object. This data is presented in plain text, making OBJ files human-readable and easy to exchange between various 3D modeling and rendering software.

The structure of an OBJ file is based on vertices (points in 3D space), which form the building blocks of the 3D model's shape. These vertices are organized into faces, typically triangles or quads, representing the surfaces of the object. Alongside the geometric data, OBJ files can also include material information, enabling the application of textures and shaders to the 3D model, providing it with color, reflectivity, and other visual properties.

Due to its simplicity and compatibility across different software platforms, the OBJ file format has become a popular choice for sharing 3D models. However, being a relatively basic format, OBJ files may not support complex features found in more advanced formats like animation data or high-level shader definitions. Despite this limitation, OBJ remains a widely adopted format in various industries, including gaming, animation, virtual reality, and 3D printing.
