Use the following options to set what happens when you select Surfaces > Stitch > Stitch Surface Points.
If Keep Original is on, the stitch surface is created on top of the original input surfaces. This lets you move the resulting surface if you are not satisfied with the result. You can re-stitch a new surface with different option settings.
If Assign Equal Weights is on, a weighted average of the selected points is performed both in position and normal using an average NurbsSurfacePoint node.
If turned on, all the points are assigned a weight of 0.5. When turned off, the first selected point is assigned a weight of 1.0 and the rest 0. The default is on.
If Cascade Stitch Node is on, the stitch operation ignores any prior stitch operations on the surface. If turned off and the surface has had a stitch operation performed on it, the stitch node from the previous operation is used. The default is on.
