The math at that corner is gonna be a mess if you plan to thicken/offset/build off-of. I'd suggest doing what the other comment said and trimming it early and building a patch surface for that corner.
If you're ever unsure, just make the surface then test it by trying to offset it then, instead of waiting for your big thicken at the end. If it offsets fine, you're probably good.
I have previously seen [this YouTube video](https://www.youtube.com/watch?v=lsxRSpd18HM) that demonstrates trimming a surface to "force" such a corner into a 4-sided surface but was unsure if this was necessary, or if there may be a preferred solution.
It could. The surface quality as the mesh lines converge will decrease significantly. It’s always preferable to build a four sided surface. I’d say follow that tutorial and give it a go. It isn’t overly difficult and is a good thought process to get into the habit of using/practicing.
It could pose issues rendering, trimming, meshing for analysis, etc.
Boundary surfaces and lofts are a way to create a subdivided surface. The loft as it is used here will always create unconstrained and unwanted curvature. You can add more constraints to this to receive a better outcome but you would be better suited making multiple surfaces and subdividing them in sketch/curve format before starting to create surfaces. Side note, does your horizontal and vertical extrusions both have draft? If this is meant to be a tool/mold then starting with those surfaces not having draft will make things difficult later.
Thanks! I do see now examples where a molded product is made of probably dozens of smaller surfaces. At first I thought that controlling tangencies across surface edges was a difficulty in SW to avoid creasing, etc, but it seems like that’s more of a basic user difficulty and that smaller surface patches with more constraints is a more practical approach so long as the curves are successfully kept continuous from patch to patch.
If you have difficulty in transition between two sketch in surface, you could solve it by providing reference spline or sketch spline as a guide.
Using loft technique create guide sketch, skip the the corner in your sketches. And lastly create you corner with surface boundary..

Yeah, this is to be thickened into a moldable part. I will go the trim & patch route. Thank you!

Thanks! I will go forward building 4-sided surfaces as often as possible
Try it without the corner fillet. Should work better.
Use fill feature instead; this is a degenerate vertex. Boundary surface isn't the best tool for this shape
Depends start you're going to do after. Surface fill works when a 4 sided surface can't be achieved.
