Can somebody help me?I

This can be solved by setting smoothing groups. If you click on 'Polygon' mode, and use the space bar and arrow keys to highlight all the polys on say the top of the wing (as an example), and click 'edit' and 'polygon properties' and set the 'smoothing group' to any number above 1. This will then effectively seperate the smoothing leaving the wing looking how it should. If you set the smoothing group to 0, that particular selected polygon or group of polygons looses its smoothness.Hope this helps?

Thanks a lot seniorcrown, that was the solution to my problem!!!Regards.
