I tried to build a bank (or dyke; http://en.wikipedia.org/wiki/Levee) using a facades file. The idea was that this thing has the form of roof. So I searched for a texture and made something like a house with sloped roof. The problem at this point is that this object is not be displayed or not all objects. I think it depends on the user settings. If I zoom out the rest of the dyke apears. But this is not useful for my scenery this thing should be there the whole time. The dyke should be there always. It was just a try and it didn't work so well. But maybe some of you could write more about it. Here is the definition of the .fac . And some Screenshots are attached, too. Thanks for some feedback.
