Conversion from U3D to PTC Creo is not supported yet :(

Universal 3D (U3D) is a compressed file format standard for 3D computer graphics data.

The format was defined by a special consortium called 3D Industry Forum that brought together a diverse group of companies and organizations, including Intel, Boeing, HP, Adobe Systems, Bentley Systems, Right Hemisphere and others whose main focus had been the promotional development of 3D graphics for use in various industries, specifically at this time manufacturing as well as construction and industrial plant design. The format was later standardized by Ecma International in August 2005 as ECMA-363.

The goal is a universal standard for three-dimensional data of all kinds, to facilitate data exchange. The consortium promoted also the development of an open source library for facilitating the adoption of the format.

PTC Creo by Parametric Technology Corporation, known as Pro/Engineer is a 3D CAD, CAM, CAE, and associative solid modeling application. It provides solid modeling, assembly modeling, 2D orthographic views, FEA, direct and parametric modeling, sub-divisional and NURBS surface modeling, and tools for mechanical designers. Its users are mostly mechanical engineers, designers and manufacturers. The app runs on Microsoft Windows.

The application is based on the parametric modeling approach, which means that it uses parameters, dimensions, features, and relationships to enable design automation and optimization of design and product development processes. Companies with family-based or platform-driven product strategy make use of this approach for what they need to perform successful design processes is a prescriptive design strategy.

The capabilities of the product can be split into three main groups, that is Engineering design, Analysis and Manufacturing. Product design processes include the ability to generate geometry of other integrated design disciplines such as industrial and standard pipe work and complete wiring definitions. Creo has numerous analysis tools which help with the development of the product which include human factors, manufacturing tolerance, mould flow and design optimization. As for manufacturing, the app has tooling options for molding, die-casting and progressive tooling design.

PTC Creo file extensions are .prt and .asm.
