Hi,I have to admit I'm totally new to scenery design so please be patient with me :-)I installed the FSX SDK and Sbuilder for FSX. In Sbuilder I was able to load background maps or satellite images and to draw a Polygon somewhere around Frankfurt Rhein-Main Airport (I wanted to create an exclude in the near forrest or to make a small lake south of the airport just for testing Sbuilder).After creating the polygon I right clicked on one of it's corners and chose "Properties". But I got no menu regarding to the type of polygon (flatten, water, exclude or whatever). And in the compile-dialog I only could start FSX, but could not compile into a BGL file.Did I miss anything? Is there any connection between Sbuilder and the SDK to be made?A little advise would be nice,Ralph

Ok, solved it:-) I simply misunderstood where to click on a polygon....
