pub fn family(format_id: &str) -> Option<&'static CadSystem>Expand description
The native format family of a stored format id: the CadSystem of the
authoring program (nx for NX parts, assemblies, drawings and simulation
files, solidworks, inventor, …). None for neutral and exchange
formats (STEP, JT, STL, PDF, images, …) and unknown ids – those are never
collapsed by a preferred CAD program.
