This is a problem I have been running into a lot: When I need to cover a region bounded by a single smooth curve, I create a trimmed surface via the patch command. But the patch command doesn’t yield sufficient accuracy at the borders to allow the patch to create a water tight seal with other surfaces connecting at the boundary. There’s probably a much more succinct way to say this, but a little tired here… I hope it’s clear enough…
I know the one solution is to extend and/or rebuild the surfaces to be joined, and then split them with one another. But when the surface’s are close to tangent, or complicated enough that extending/rebuilding makes a real mess, it’s not an option.
Why wouldn’t the patch command, in the first place, allow for tolerance control to enable water tight connections?
Any thoughts on an alternative approach?
I have the same problem when the boundary to a region is triangular… I wish there were a 3 sided surface…
