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.

A SKP file is the native file format for the popular SketchUp 3D modeling application. SketchUp is a growing platform, popular with industrial architechs and 3D design enthusiasts alike who like the ease with which complex 3D models can be produced.
The SKP format is capable of storing complex 3D models and their associated geometric data, such as vertices, edges, faces, materials, and much more. The format is well supported, and it receives updates containing new features on a regular basis.
Due to its popularity, the SKP format is supported by many 3D modeling applications via an import option, and where an import option may be missing, our own SKP conversion tools can convert to and from the most popular 3D formats.
SKP Converter Capabilities
Our 3D conversion tool does not support color or material information in SKP files, so your file will not contain any color information.
