I suggest you see the manual: ScenarioEditor.pdf (in orbtier\doc folder)
But in a nutshell:
If you want Scenario Editor to list your vessel you must copy or move (this is usually enough!) the vessel's .CFG file (e.g. Clydesdale.cfg) into "\Orbiter\Config\Vessels" or any folder below that...
SE only considers .cfg files which are in "vessels" folder or in its subfolders.
I am not sure how to circumvent the problem with vessels, that use .INI configuration and depend on spacecraft.dll...
Advice on that would be welcome too.
