The 3DM file format is a 3D Computer Aided Design (CAD) format primarily used by the Rhinoceros CAD software. It enables the storage of both simple and complex 3D models within a standard package and has found many uses within the architectural, engineering, and manufacturing arenas.
The format allows the storage of 3D model geometric data, including mesh and texture coordinate data. This 3D data is stored in the NURBS format, allowing complex objects to be represented with high precision.
Although primarily designed for use with the Rhinoceros CAD software, 3DM files enjoy support amongst other CAD software, with many supporting the import and export of data to the format.
3DM Converter Capabilities
Our 3DM 3D Model/Mesh tool does not support any colour material data contained within 3DM files, so the converted file will not contain any colour information.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.
The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.
One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.
