Surface Curve going to Zero Radius and Tangency

[Tom_P]

best tipp above by pascal:

@pascal

idea of primary and transition surfaces

and also some nice example in an older post

@pascal

I’d be inclined to try to stick it togther more like this

then do some trimming.

there is also a lot of info already in those older topics.
did you try to work on those ?

Bad Surfaces

This is a problem I encounter frequently: In the attached I have a polysurface with Four three-sided holes. Two have been filled in. I creates two surfaces to fill the holes (red) using sweep 2. The objective is to have the two of the sides tangent. I have tried edgesrf and networksrf for this type of problem and it never comes close. I have tried cutting a triangular piece out to get a 4-sided hole but have never gotten a shape the looks close, Problem Bad Surface.3dm.zip (779.8 KB) [Vie…

Bad Surfaces

what s the result of those other / older topic ?

but I agree - it s hard to understand and learn how to get a nice nurbs-Surface layout / hierachie for these kind of geometry … if someone can point to a nice tutorial / theory about this - I would appreciate it as well.

kind regards - tom
