Boundary Blend Tangency Issue
Boundary Blend Tangency Issue
(OP)
Howdie.
I think I'm brain-farting here, but can someone tell me why I can't get one boundary blend to be tangent to another, as I am attempting to do in the attached image?
Any replies would be greatly appreciated.
Best regards,
treddie

RE: Boundary Blend Tangency Issue
Also you could do a shaded curvature analysis to see if any of the ends of the mating surfaces have any small flips near the ends. I have seen this before and the resolution was to trim out the bad sections.
Hope this helps,

RE: Boundary Blend Tangency Issue
Yes, all are tangent. And no flips.
But I think I just stumbled on why it failed. Apparently in ProE, you can't use the tangency or curvature option if the boundary curves extend BEYOND the surface into the neighboring surfaces you are claiming as tangency surfaces. I had originally extended them to help make sure the new boundary blend followed the desired shape more closely by including that extra "training" info. But now that I think about it, that pretty much conflicts with the tangency constraints I was trying to achieve...the tangency constraints would have done what I needed far better than just trying to train the shape via the extra long, bounding curves.
