This is mean family without host for example different furniture. It does not require modification geometry of host element.
System families contain family types that you use to create basic building elements such as walls, floors, ceilings, and stairs in your building models.
Walls, floors, ceilings, and stairs are not families, they are reading and represented as the classes instances. Revit does not require loading a family for creation such elements. Family for example are windows, doors, columns, etc. For creation instances of such elements in Revit you need to import a Family in the file.

Any file beginning with the 2011 version can be opened. Automatic conversion to the latest version is implemented for the 2015 file version and higher. Conversion to previous versions is not supported.
A template file must be used for creation of a new .rfa or .rvt file.
All Revit formats are supported: .rvt, .rfa, .rte.
At this moment there are no wrappers.
Exports are available to COLLADA, JSON, PDF, OBJ, STL, raster formats, and SVG. Only part of the available information is converted (meshes, materials, textures). Other high-level data cannot be exported because such data cannot be saved in the listed formats.
