trying to make an eye patch using surfacing.. I've tried lofting and boundary surfaces, and so far seem to have found boundary surface to work a little bit better, but thicken has given me a lot of problems and I've had to trim out some of the surfaces that didn't "tangencize" so well.. see attached part file..
Also thicken didn't leave a flat edge on outer rim.. I suppose I can trim with a plan to get it flat? Seems like a lot of extra steps, but I've not done much surfacing, so maybe that's the nature of the beast.
Is there a better way to do this?
