Zebra gives a bad grid at edge of the smoothing surface

[Modeler3D]

I have created two symmetric surfaces, have executed BlendSrf, have reflected the smoothing surface, Join and I watch a zebra - result very bad!

There are surfaces:
1.3dm (2.3 MB)

At surfaces good continuity, but a zebra bad - why so?

Hello - I’m not seeing that here, with your mesh settings… but try analysis (not shading/rendering meshes!) mesh settings like this:

Now everything is good… Thanks!
