Do you have any part file to see that makes any differences in selection of Optimize option in Fill Surface. Because I tried with many part files I cannot see any differences.
Yes, I believe I illustrate this in one of my webcasts. The Optimize surface is an option that employs a different algorithm when solving a patch boundary. My understanding from my colleague that implemented it when I worked for Dassault is that the Optimize option uses a "coons" patch versus the proprietary DS solution. In layman's terms the difference is how the Fill derives its Isoparam direction from the surrounding faces. What's special about the DS solution is the direction of the Isoparms is generalized so that it can be adopted to three or more than four surrounding faces (so as to avoid degenerate vertices). The Optimize (like the Boundary surface) cannot do this but derives its Isoparms from the surrounding faces. Also, I believe if it is a 3 sided or 5 sided requirement that the user gives, that it (Optimize) is automatically turned off.
With Optimize checked. Notice how the Isoparms are flowing in a direction defined by the patch boundary
With Optimize unchecked. Notice now how the Isoparms are generalized and not following the specific direction of the surrounding patch.
A six sided patch: having Optimize checked or unchecked makes no difference.
