algorithmic modeling for Rhino

Isoline problem

Hello people,

Sorry, but I need small advice. I want to create couple of isolines and put them between this two isoline (which are defined in rhino). This isolines are manhattan (10m terrain hight and I need to create 1m terrain hight). But I need to create this lines just inside curves, which are defined in the rhino. Im using TWEEN CURVE, but the isoline, which is generate by this operation, is just one, and sometimes is leading out of the lines from rhino. Basically I need to create something like obr1.jpg.

I hope its understandable :))

Thank you so much for any advices..... And have a nice evening

I have done something, but it is not a simple thing. You could try with medial axis but I doubt it can generate 10 isolines ! The solution use Anemone so it is iterative. 

The second script generates many isolines. But it is like a river it tries to go straight !! 

I hope you will find someone wiser than me.

To do multiple tweens you can use Range component after you rebuild the curves 

but for specific 1-meter height, you can use contour component after lofting between the two curves

I hope I understood your question right!
