Full round between three surface
Full round between three surface
(OP)
How I can create in UG full round between 3 surface ? It possible? Now i use for this I-DEAS v11(three surface fillet feature) or CATIA v13 (threetangent filet feature).

P.S. Sorry my bad english

If you want a curvature continous 3 surface blend, then use associative bridge curves or associative splines to build the wireframe of the blend, then make a through curve mesh free form feature or use Shape Studio's Studio Surface.
As far as I know, I don't believe either of the blends you listed above in your first post have curvature capabilities, do they? If so, then why is one called tri-tangent? ;)

1- the problem of drawing the correct midsurface-parting curve may be solved by using an isoparametric curve with u (or v) equal to 0.5.
2- I'm used with hydraulic turbomachinery, so maybe this problem affects only flow of compressible fluids, but in our field the LE curvature continuity is never a "must": are you absolutely sure that a D2 discontinuity would affect LE performance, as far as D0 and D1 continuities are guaranteed?
3- Anyway, for this particular task I would prefer the method described by nkwheelguy: much more control, and it allows LE shapes different from the single-radius round (ex: parabolic, ogival, etc...)
