Hi Dinaharchery,
Suppose you're trying to trim surfaces. Well, if it were planar surfaces,
it wouldn't be too difficult. I did a similar thing by creating windows in a
wall, using GeometryArrya. You just recreate the array including the
new points. However, if you trim a free form surface, you have to take
the surface points bewteen the vertices in account. As you will agree,
ther are a lot more calculations needed for that. If you are using Bezier
surfaces, you could possibly try to create a Bezier curve at that trimming
edge and get its vertices. Then you may use these vertices within your
recraeted GeometryArray. For B-Spline surfaces it might be more
difficult.
