I have not tried to apply a boolean union, other than simple excluding parts to create holes. When the wing is finished, is it all joined as one object in the vertex medeler? It looks as if it is. Very nice work. I can see making one feather, rotating, stretching, etc. but how did you use a boolean union? It looks great. I always appreciate seeing the wire frame. I'm starting to turn into a wireframe junkie : ). R.

Never Give Up!
