With VDA -FS, we describe a data format for the exchange of geometry information between different CAD systems.
VDA -FS is the abbreviation for Association of the Automotive Industry - surface interface.
With this interface, only 3-D information can be transmitted and no drawing information such as IGES or STEP, with the possible.
VDA -FS was and is mainly used to convert 3D data between CAD systems such as CATIA, Unigraphics, Pro / ENGINEER and Tebis. Some measuring machines detect contours in this format and provide the data so that CAD systems are available, so for example, a SET-ACTUAL comparison is possible.
VDA -FS Version 2.0 includes the following elements:
- Geometric elements point
- Point sequence
- Point - vector sequence
- Curve on a surface
- Limiting surface
- First and final labels
- Transformation matrix
- Transformation list
- CAD data format
