Hello.
When work with difficult shape in part, often happen to work with surface body. Sometimes appear many small holes in faces.
The planar holes patch easy use Boundary Patch.
Not planar holes possible patch Loft command, but Loft require two object minimum. Sometimes, for this happens to split face on two halfs.... This long time and heavily enlarge the tree of the parts building.
Proposal:
Create versatility command "Boundary Patch 3D" instead of "Boundary Patch", which created spline-face. Besides possibility patch 3D holes, this command must have additional options:
1. Patch all - automatic search closed curves.
2. Tangent nearby faces.
3. Heal - create solid body after patch, if this possible (Stich).

I think, that accelerate job designers and engineers, particularly by design complex casting part.
