Grasshopper

algorithmic modeling for Rhino

i am working on orienting and tagging a serie of closed curves. i used the Evaluate Surface Compound but i am having a problem with the xy point orientation on the sections i made. they simply do not share the same orientation as shown the photo below.

i am trying to orient the sections with the orientation tools but no success. i need the sections to be oriented accordingly flat on the xy surface.

any help would me appreciated.

p.s: i am using the WIP on Mac.

thanks,

Zadig

i appreciate a lot your help. finally i have some one can help me out with my work. it did indeed  solved the main problem but it is repeating one section at the end of the list, and the tagging order of the sections is not accordingly with the main shape. i do not understand why. 

thanks a lot Kim

Check this.

do you know why this happens?

thanks again kim. 

If you divide a curve 10 divisions with "Divide Curve" component, then the output point count =10+1=11.

So, your section curves are 10, and they don't match up.

If you want to match these two list, you should cull one of last items.

i got it :)
