I am trying to replicate the work that this individual published in their thesis:

http://fluids.me.washington.edu/theses/riley-thesis.pdf

Specifically, the work on pages 11-16 of the thesis (pages 23-28 of the PDF). I have got everything up to the **Filled Surface** step. This step is supposed to patch up the five sided section that cannot be lofted. I cannot get it to create a mesh. I have played with the various contact/curvature/tangency combinations of those edges to no avail. I made a generic model to get the steps down before I started working on the anatomical sections I need to apply this to. This is what I have:

The following views are of the other side of this branch, where I tried to loft the five sided section closed with a four sided loft with one edge free and a second four sided loft:

However, this produces a seam at the saddle edge and at the straight lined edge that borders the two lofted surfaces. I have attached the file that I am working with. I am trying to generate a surface for this section in the same fashion as this tutorial:

The goal is to produce a surface that connects the 5 faces with propagated tangency and/or curvature from those edges to minimize any seams in this region. Thank you.

I figured it out. This is what I did:

1) Ingest a healthy dose of caffeine and reread post

2) Use

Knit Surfaceto join all surfaces on the model. There were a few gaps:3) Use

Filled Surfaceto patch up that five sided headache. I made every constraint "curvature."Final outcome:

The ripple is due to to branching section having some high curvature in the cross section that was propagated to the surface. Smoothing the cross sectional sketch splines should reduce those surface ripples.
