U3D Universal 3D File

An open-source compressed file format that was initiated by the 3D Industry Forum. U3D is designed to store three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates. Here are some of the key features and advantages of U3D:

  • 3D PDF Integration: U3D enables the generation of PDF documents that contain interactive 3D data. This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document. 3D PDF is a widely used and supported format that can be easily shared and distributed.
  • U3D File Converters: Autoconverter and Automesher Application are capable of reading and writing to and from the U3D file format. This allows you to convert your 3D models from various formats, such as STL, OBJ, SKP, DAE, STEP, and others, to U3D and vice versa.
  • IFX Conversion Library: Our U3D file converters use the publicly available open-source IFX conversion library provided by Intel. This library is a powerful and reliable tool that enables the conversion of 3D data to and from U3D.

STP STandardized Exchange of Product File

A file format used for the exchange of 3D data across various computer systems, including CAD, CAM, and CAE, in a standardized format. Some of the benefits and features of STEP files are:

  • Compatibility: STEP is widely supported by many software applications and platforms, making it easy to share and collaborate on 3D models across different domains and industries.
  • Accuracy: STEP preserves the exact shape and dimensions of 3D models, unlike some other mesh formats (SKP, OBJ, or STL) that may introduce errors or distortions during conversion.
  • Materials: STEP file format supports colors per assembly. However, it lacks an alpha component. This means that any transparency effects applied to 3D models will not be visible or preserved in the STEP files.

STEP Files Converter: STEP files can be very large, especially when they contain complex or high-resolution 3D models. One way to reduce the file size is to use Autoconverter software, which can utilize the faceted BREP representation, potentially saving up to one-third of the file size. It uses the Open Cascade framework, ensuring compatibility with the latest STEP standards.
