>a) I cover the old lake with land with the funktion "Cell>attributes->Area attributes". I use "Fill1x1/LWM" and check>"Land".Do you mean to use the New Object Button and then digitize a land polygon? I do not know what you mean by the Fill1x1. Where do I find that? I just created a land polygon using texture 30 crops, changed the name of my exclude file to aa.bgl but I see no difference. The lake is still there. >Hope it helps,>Edgar

Placed a land polygon over the existing lakes and raised it substantially above the surrounding elevations to see if it really was part of the scenery. It clearly is as can be seen in the screenshot below. However, even with my exclude file renamed to aa.bgl the existing lake remains. Can I rename the exclude after it is generated or do I have to go back to the very beginning and create a new project with the exclude file named properly at that point?http://www.bbbrown.com/bbbrown/images/jpgs...erexcltest3.jpg
