thx for reply ... but there is a problem ... it works wonderfully if you have 2d curves but if you add also z-direction it doesn´t fit ... I mean something like this ...

You must control the initial point and direction of the lines.

Quite interesting. It still produces a surface with naked edges though. Once baked they can be joined in rhino to make a single surface which can then be capped on the planar edge or patched and joined.

Is there anyway to actually join those edges in GH or will there always be that slight gap caused by the 2 subcrvs?
