In my current scenery project (CREST IV) i created a hangar way above ground and it would be nice to have the hangar floor as a landable surface.Can anyone point me into a direction how i could do this ? Would it be enough to assign a ground type (like concrete, asphalt) to the polies that make up the floor ?RegardsDoc

Hi,Here is the SCASM code to hard a polygon of 6 vertex. You needto enter the and for the "cennter" of your polygon,in the GRP() and your altitude in meters in the SetElevation().You need to enter the points in clockwise order. If you are generating your roof with a graphical tool, you can take the coordinates of the vertex from the Point() list of that polygon, removing the midle parameter (eg altitude). In that case you can take the and for the GRP() from the RefPoint() parameters.Regards, LuisGRP( )Area16( g 5 5 ) RefPoint( abs : 1 d 0 0 V1= 0 V2= 1500 E= 0 ) SenseBorder( : -1008 -875 ; 0 927 1081 ; 1 1065 944 ; 2 -890 -1031 ; 3 -947 -1042 ; 4 -1040 -951 ; 5 ) SetElevation( 58 ) ; 58 meters above sea levelEnd16

Thanks for the hints, Luis. I think it brought me into the right direction. I'm working with gmax and won't use SCASM. But i got the FS 2000 Scenery SDK and found the BGL Opcodes that correspond to the SCASM commands you mentioned. With a little modification to mdlcommander i might even be able to automize recognition of elevation polies in gmax models and post process corresponding asm files (I'm just too lazy to fool around manually for every export i do ...)RegardsDoc

Hi Doc.Use fsregen.Create a polygon in your gmax scenery, and process it specifying "Landing area". (see the pdf on how to create a "special material" for your polygon).George
