Hi Klingbeil,

> how can i do what you did to make it work, for future reference?

Well, curves will only join one end to another end, they won't join into branching patterns like you would have there if you just had a bunch of individual lines.

So instead of making a pattern of single lines, for something like that you're better off making a single surface and then replicating that surface instead of replicating individual lines. Then make sure not to repeat any surfaces exactly on top of each other, that's what seems to have caused the problem in your original pattern.

Let me know if you still have any problems getting it set up.
