Help needed for joined curves and loft

Hi
I am working on a definition where I use joined curves in a loft to create a surface. In grasshopper 0.5 I had no problems since it read the joined curve as one curve. When I updated to 0.6 I cant use my joined curves in the loft since it does the loft between the two joined curves instead of between the joined curve and another curve. Hope it makes sense. I expect it to be a tree problem, but even if I flatten it still does the loft within the joined one. Since this is my first definition I am probably not doing it right - help needed.
thanks

The major difference between 0.5 and 0.6 is the DataTree addition. Data can now be stored in trees instead of just lists.

If your curves don't join, that's probably because they are in different branches of the tree (Join only operates on the items in a single branch at a time).

You can see the structure of the data tree by plugging the data into a Param Viewer.

There's a bunch of components available to modify the layout of a data-tree, or you can flatten the tree at any input parameter you like.

Hi David.
Thanks for the answer. Still having trouble though. if you see the attached picture it shows (in rhino viewport) the loft it is doing on the joined curve alone, which is not what I want since it should understand this as a single curve and therefore not be able to loft it. I have isolated the part of my definition that I cant get working: I have a planar curve that I split using a plane. Then I chose the part of the split I want by using a "list item". Then I use a "join Curves" to join the split part (of the planar curve) with a non planar curve. when I put that into a "loft" I get a surface, where in 0.5 i didn´t get a surface before i added more curves into the "loft". I have added params viewers in the picture so you can see the paths.
Thanks
