This one has me a bit stumped....When I patch this surface, the patch shows up in a position no where close to the geometry it is generated on. I have gone back several times and recreated the problem from different parts of the history. I suspect it is because I aligned the based body to a plane with the align tool and it garbled something up?
I would not work from imported geometry wit questionable curvature.
Cutouts and fillets should be made as late in the design process as possible. First create the main geometry, then add detail.
It makes no sense to work with tangency ribbons and then not using the appropriate tangency settings in the loft dialogue:
I am only this far in the timeline:
Edit: Looks like to did it - the tangency settings - correctly in come cases but not in others.
I am surprised that Fusion 360 even creates a patch. Usually that requires a closed loop, of edges or curves selected in the right order.
However, there is a segment missing in this case:
I think an overbuilt and then trimmed surface will create much better quality than a boundary patch.
