I have been searching the forum here, but haven't been able to locate anything on this, but I need to remove the flatten from an airport. I know I could remove the bgl file that contains the flatten for this area (or edit it), but I may distribute the final product (if it turns out the way I want that is), and I don't want to have to make any irreversible modifications to the end users install to get it working.Thanks,Bruce

Someone else (Dick?) correct me if I am wrong, but I think flattens can not be excluded.Arno

Hi Bruce and Arno.Arno is right, there is no known way to exclude a flatten of an airport.But you can reflatten ( remesh ) areas. This can be done with SCASM code ( "flattens" or Area16n polys ). It can also be done with transparent LWM polys with a height designated.If the area is small, it's not too big a chore. I usually write SCASM flatten polys ( and scenery excludes ) by hand. There appears to be no significant advantage to using LWM's to flatten.Steve Greenwood wrote a small program to write flattens.http://www.fs-traveler.com/flatten.htmlThe resulting BGL can be in your scenery package, and when your scenery is active, the reflattening will be active.Dick

Thanks for the reply, that was what I had suspected and of which I was afraid. The problem is that I am trying to make the runway have the proper slope by creating the runway surface in the mesh, and the only way to do that is to eliminate all flattening. I already have this partially done by deactivating the flt*.bgl for the area including my airport, but this eliminates the flattening for all airports in the area. Bruce
