Years ago in an old Sim....2004 l had down loaded a few blg file librarys they had planes, cars, docks, etc.
l had also down loaded a small prg that i could use to place these files in the sim. eg..... l could place a dock and cabin on a lake water front so l could dock my DHC-2 when l flew in, it was very easy to do, is there anything similar available to do the same thing in P3D?
