Three-dimensional image created using the 3DCT 3D image compression software or the 3DCT modeling software plug-in; contains a compressed 3D image; used for reducing the file size of standard 3D formatted images and sharing them over email, which is useful for design reviews.

3DCT can create 3DC files from several formats, including .STL, .PLY, .OBJ, .3DS, .LWO, .DXF, .VRML, and .OFF. It also can export Rhino .3DM files if the plugin is installed with Rhino. NOTE: 3DC files can be viewed with the free 3DCT Viewer program.

GPS data file used by iGO software; contains 3D building data and corresponding metadata; saved to the \iGO\content\building\ directory of the navigation unit's storage card.

NOTE: NNG, the developers of iGO products, were formerly known as Nav N Go.

Training course file used by Computrainer 3D, a simulation software for RacerMate's CompuTrainer and Velotron electronic bicycle ergometers/trainers; contains a racing track, including road and elevation characteristics; used for storing actual real-world courses, as well as rehabilitation courses for physical therapy.

RacerMate software interacts with a stationary exercise bicycle and responds to motion as the user pedals and steers the bicycle. In this manner, riders can train for cycling events using simulation.

Project file created by RoboCell, a program used for SCORBOT robot modeling and simulation; stores a configuration of 3D robot components in a "workcell;" allows a SCORBASE program to be run visually in a 3D virtual environment.

RoboCell is used for integrating SCOREBASE robotic control software with 3D modeling and simulation capabilities. It is used in educational environments. NOTE: Robocell has been discontinued.
