Loft in Grasshopper works different to the loft in Rhino?

Hi there,

I’m pretty new to Grasshopper but managed load a Scan of a foot into Grasshopper, then divide it into points which i turn into Nurbs that should be loftet.

Up to the Nurbs everything works fine

But the loft has kind of a rotation in it as you can see at the pictures!

As i baked the loft i saw that the line in the loft (I am not really sure what it means, probably starting points of the curves?) twists a bit as it goes down to the heel of the foot

Or at least it has not the same line as the loft of rhino itself (where also the rotation and also the resulting wrinkle does not appear)

My question now is:

• Is there a possibility to loft in grasshopper the same way Rhino does?

• If not, is there a way to edit the loft of grasshopper such that the rotation does not happen anymore?

Thank you for your help!
