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.
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?
Can you upload the curves (either as a 3dm file or internalised in a GH Curve parameter)?
It could be a problem with Seam Adjustment. For closed curves the Loft command may perform some additional steps to try and align them more neatly, but it’s hard to know without seeing the difference myself.
Grasshopper does have a component for adjusting curve seams, but figuring out the exact seam parameters can be tricky. I used a Curve CP component, but it’s still wobbly:
Here’s a more involved solution for creating smooth seams. First I do what I did already, but then instead of using the points immediately, I create a polyline through them, smooth the living daylights out of that polyline, then use this smooth polyline to find new seam points.
