Need the code to get access to the properties and isolate the parts and save it 1

I need the code in C# to open Catia, open a part or assembly, open links, isolate all the parts, save the assembly and close. Could not find any help from documentation. Tried recording a macro, does not record the isolation process. Any help would be greatly appreciated. Need help with the to access the active Link window to isolate the parts and save them.
