Hi Brash,

Could you please post the .3dm file of the profiles so that the guys here could help you out better, it's difficult to help out from screen shots.

Cheers

Yes, could you please post the .3dm file of at least the object set in question?

Try this: 1) make sure that the little ring is a round circle and is also basically tangent, or relatively planar with the ends of the long curves.
2) go back to the number of profile rings you had on the main body, but add two extra long curves in the remaining quadrants to define those sides.

See my tutorial: http://moi3d.com/forum/index.php?webtag=MOI&msg=5188.1

It will teach you how to make the best of your Network shape. :-)

Hi brash yes as others mentioned it would help a lot if you could post your 3DM files instead of only screenshots.

Often times putting in too many sections adds a kind of "pressure" onto the system which can make for undulations, using fewer profiles can help get smoother results.

Also from your screenshots it looks like there is fairly uneven spacing in some areas, try to make things a bit more evenly spaced instead of having one profile with pieces close to each other and then suddenly swinging far apart.

But if you could please post your model file it would make it a lot easier to experiment with it and give better suggestions.

Hi all and thanks,
file attached.

Need:
1.smooth solid
2.connect two parts with fillet.
3.connection profile make rounded.

pls help)))

Hi Brash,

Take a look at the attached file:

I made another long profile curve derived from the one you had in the center, and I mirrored it.
So now I had more profiles to define the greater shape from more sides.

I took out many of the profile rings so that network would not have to negotiate so many.

I replaced the small ring at the ends with a perfect circle, because you basically want the network grid lines to meet at the 'same time', so to speak.


See if it's more to your liking.

Good luck.

Mike

Thank you very much!
you tip and MACH-18 tutorial very helpful.
i did mirror>add line>trim line and left side>repeat trim on right side>fillet 5 mm
but still problem:
1. smooth connection two sides
2. no constant thickness
pls help

Hi Brash,

To get a smoother transition, trim away more surface so that there is a gap, then Blend the two open edges.

You'll have to play with the curve shape that trims the network surfaces to try to get the blend to be more continuous.

The unwanted undulations in the resultant network shape could be remedied by either trying a different Network mode or working with the profiles.




Personally, If I was trying to make a more exact and uniform shape, I would have made the main body with a simple sweep of the profile ring along an 'S' shape, and then used Blend or the new N-Sided to round out the ends.

Good luck.

Thank you, Mike!

Also one of Mike's previous mini tutorials for this kind of trim + blend technique for Y branch type things:

Ehh... That's one I still want to improve on.
