What is a C3D file?
A C3D file is a 3D model saved in the C3D Labs binary format, which is a CAD format used in architectural and machine building industries. It contains geometric object data for a 3D model, such as curves, points, triangulation, assemblies, and bodies. C3D files are the primary files used to exchange 3D models using C3D Labs software.
If you receive a C3D file, you can open it with C3D Viewer, which is available to download for free. The program enables you to zoom in and out, pan, rotate, and orbit the model. You can save different views of the model in the JPEG, PNG, BMP, and TIFF formats, which allows you to share your model in a more widely supported format. The program also can be used to view other formats, such as .STEP, .IGES, and .STL.
NOTE: C3D Labs was formed in 2012 out of ASCON (one of the first Russian CAD developers founded in 1989) after years of developing the C3D kernel. They are located in the Skolkovo Innovation center outside of Moscow.
File Type 2Coordinate 3D File
.C3D File Association 2
Data file saved in the Coordinate 3D (C3D) format, which is used for storing biomechanical information; stores three-dimensional motion capture data in a compact binary structure; used as a standard format for biomechanics data storage.
Coordinate 3D was designed for flexible and extensible data storage. It allows users to store and modify custom parameters in addition to the standard biomechanics parameters and raw data.
The C3D.org website, which is the main resource for the C3D format documentation, is hosted by Motion Lab Systems.
