U3D files are a 3D model format designed specifically for use in conjunction with PDF documents. The U3D format stores 3D model data in a manner that allows the file to then be embedded within a PDF document, enabling rich 3D content within a standard PDF.
Within a U3D file are the various data elements that make up the 3D model, including vertices, faces, normals, and texture coordinates. Along with this basic geometry, the face materials are also stored, which describe how the 3D object's surface should be rendered.
Support for exporting 3D content to the U3D format can be found in some 3D modeling software; in particular, the popular modeling software Daz Studio contains a U3D exporter.
U3D Converter Capabilities
Our U3D 3D Model/Mesh tool does not support any color material data contained within U3D files, so the converted file will not contain any color information.

The BLEND file extension is the native 3D modeling file format of the ever-popular Blender 3D modeling software. The Blender format originally came into existence in late 1994 and has since evolved into the advanced 3D format we have today.
The format stores complex 3D mesh data along with textures, animations, lighting, and other information related to 3D scene rendering. The format is popular among those creating 3D videogame graphics and animation sequences due to its advanced features and ease of use.
Along with Blender, BLEND files can also be imported into other popular 3D editing software. The open-source nature of the format allows third-party plugins and scripts to be created to run within the Blender editing environment and extend the format's capabilities.

Our 3D conversion tool does not support color or material information in BLEND files, so your file will not contain any color information.
