surface Join 1

[fzvnpg]

I am attempting to merge, sew, combine faces and quilt without having a line showing during the reflection analysis. now these are customer supplied surfaces and we are trying to avoid rebuilding each one. the errors we get are can't do that to a trimmed sheet (even though I removed parameters)or the can't find mergeable faces, face is not parametrical-rectangular.

Any ideas?

That middle surface is going to be tough to Quilt, in my opinion. If it were me, I'd just extract the Isoparametric U & V curves and rebuild. Watch the green surface - it's 5 sided. Get it to 4 with untrim if possible.

indeed but the full surface is a wave runner.... several hundreds of these... that is what we currently do, rebuilding these takes days...looking for short cut ... and filling the holes between sheets etc.
unfortunately its next gen so can not show...

I completely understand - been right there with you, getting similar types of A-surface data albeit on a smaller scale (aluminum wheels). You're talking major cleanup and unfortunately with styled surfaces, it does require the time and effort to do what you're wanting to do. You'll have easy spots and where there is direction change and curvature change, you're going to run into issues and have to rebuild just to get the face edges the way you want them. It's not as simple as we would like, I know that. Unfortunately it's just the nature of the beast and I know it's very frustrating.

why do you need to "merge, sew, combine faces and quilt" ?

I need a water tight solid with a Class "A" surface on the outer and inner surfaces

Not many shortcuts for Class A other than recreation or Quilting into larger slab surfaces. When Quilting like that, you're still going to have to analyze the surfaces to make sure the output is smooth and meets the customer's intent. Went through it for 10+ years at my previous employer and it's just the nature of working with that type of data. Get used to using Bridge Curves, Through Curve Mesh and understanding the curve and face analysis tools in NX.

In my opinion, your best bet is to talk to the customer about their modeling techniques and explain why you need them to adjust their methods - if you word things carefully and are able to show a cost savings (i.e. time) then they might just listen to what you have to say. I doubt they'll be very receptive, but you never know until you try.
