Hi Folks, the next nebwie in Scenery Design. :-shy I have started my first Airport project. I will make a little airport in the switzerland. I have found a beautiful place. The default Airport "ALPNACH" LSMA.So i have a little problem with the default flattenfile from the sim. The Flatten is in the follow file: "fl950150.bgl". Is it possible to exclude or delete this on flatten polygon for the Alpnach Airport. I have tried to delete this polygon from the default file and recompile this. But after the compile, i have many elevating on the other default airport. I work with SBUILDER. Have many people an idea, how i can delete this Flatten Polygon?

> ... But after the>compile, i have many elevating on the other default airport. Hi Manfred,I assume that you append the LWM BGL file into a new project and you edited the flatten polygon of the airport in concern. You do not changed anything else and you generate a new BGL.If you mean that the flattens on the non-edited airports get changed, then it should be a bug in SB.Regards, Luis

Should i have again this problem, so i will post a screen.

Hello Luis, sorry, false alarm. just this moment i've test it, and what can i see. It's ok. I have started a new project, append the fl950150.bgl and delet the flatten polygon from alpnach. Then i compile all other polygons and save it and restart the sim. Now it's all ok.Sorry for the wrong message.
