I have the following shape. It was created by creating fourends and then creating a surface using either surface loft orboundary surface between each of the four ends. Each surface iscolored a different color so you can tell what is going on.

I need to "fill in" the top dimple in between the four surfaces sothat everything between there is smooth - almost as if this were areal part and you poured water or melted metal into the dimple. Thesurface would be tangent with all four of the surfaces at the topof each surface. It may or may not be a plane.

Does anybody have any ideas?SolidworksSurfacing
