I am happy with SceneGenXexe,But there is a problem with the Flatten at one end of my Runay,it is thus,the last 100m is floating and have tried layer 3 but fear it will not make any difference to go on perhaps someone can help,the MSL is 925' and worked perfect uptill the last 100',regards Patrick.:-hmmm

No worries, found what i was not doing,what i was not doing was firstly including the fdefault scenery airport Directory text,flatten and exclude work great.Patrick.
