Saving the Hierarchy
The kinematic hierarchy can be saved by exporting it.
Use the 
button to export the hierarchy.
This action saves the hierarchy of nulls, vectors, and axes as a KKI file. The parenting of surfaces to the hierarchy parts is not saved.
KKI files can be reimported into this database, or imported into any other P3D database using the 
button.
When a kinematic hierarchic file is imported, its nodes are added to the current kinematic hierarchy. If you wish to replace the current kinematic hierarchy with a saved hierarchy, delete the current hierarchy parts before importing.
