generative modeling for Rhino
Did you try not to check "jagged edge"? I don't know Daniels logic behind his suggestion, but I can recreate his own perfectly joined mesh only with this option set to false. Set it to true and the vertices at the edge will no longer align.
Hannes, you are absolutely right. It works perfectly fine with the "jagged seams" unchecked. I'm not sure why Daniel suggested to set this option to true. In either case, thanks a lot for taking a look at this!
Oops, my mistake - sorry. I think I must have mixed up the 'refine mesh' and 'jagged seams' options when typing that. Thanks for picking this up Hannes
I thought I was going crazy... but now I will remember for sure ;) Thanks again Hannes!
