rotate either your sphere or your splitting curves so that they coincide with the seam.

thanks Danny,

unfortunately these curves are the result of another process and will vary always location. I also need to consider the option of having just horizontal or vertical curves.

Probably I need to set up the sphere in a way that it adapts to this variable curve alignment.... I'll think it through...

many thanks,

k.

Another way might be to rotate one of the other subsrfs to replace the split one.

I may have a fix, but it needs testing.

I solve the intersection for the splitting fragments and the domain start/end curve(isocurve V on u,v = 0,0). The fragments with only one intersection are joined.

 

Edit : too much joining with this, need to join only those intersecting on the domain frontier.

Sloppy piece of code, and it returns Breps instead of trimmed surfaces.

thanks, I had a look at the file...

I understand the process... theoretically it should work but unfortunately the breps are still separated at the sphere domain edge..

let you know if i find a solution

 

thanks!

Fixing the fix of the fix! It should work at least on my example.
