I need to create [a] surface[s] to fill in this oddly shaped area.
The red curves indicate the end of the surface where other surfaces meet at right angles. The purple curves indicate the end of the surface where it mates up continuously with the adjacent surface. The blue curves are tangent with the adjacent surface but are flexible in their position.
This illustrates that surface. Here I am dealing with the inside (dark area of the starboard propeller) of the twin keel:
Obviously, this is an oddly shaped piece of steel bent into shape. If I use the PATCH command I can visualize a surface that is roughly what I want. The problem is that (at least within my skill) the surface produced does not match the outlines within the tolerance need to join the surfaces at the edges.
If I use NETWORKSRF, EDGESRF, or SWEEP2 I get something like this with excess bends:
My question: How can I fill this area is something nearly as smooth as what Patch shows but matching the edges within the tolerance?
