NX 10 Surfacing G2 continuity help needed

Hi all,

 

At the moment im drawing a rubber wristband in surfacing.

Lately i am having difficulty getting G2 continuity between surfacing. Although all features can do G2 and don't give errors, the end result ( face analysis - reflection ) show strange things between the surfaces 

I tried already a lot of different ways to solve this but still didnt get it working how it should.

 

 

I even tried to see how i could solve this problem by only drawing a small part of the wristband and even here with several features i didnt manage to get this G2 between surfaces

- 2 surfaces where 1 is G2 to the other, reflection shows strange things between the 2.

- Create 1 big surface at once, surface doesnt follow the curves at all and weird reflections

- draw half the surface to mirror it, still didnt work

 

It's important that the shape is following all the curves.

Attached I put the small part file. Anyone that can show me how to solve this?

Hey,

 

Thanks for your reply.

 

I checked the file and still see some things when i do a surface continuity analysis where appearently G1 and G2 is not perfect. See image below.Not G2 surface.PNG

Hi,

Is there any specific tolerance  you seek for G2?

For tighter tolerances you need to break the transition surface in more than one patches.
