Hi lee,

you can intersect a shape with a collection of planes, then extrude the intersection contours by the distances between planes, that should give you a similar result (see attached).

Hi David,

I have a question, I have a topographic map with contour curves, created with the ELK plugin for GH but they are not closed. Is there a way to close them and use your definition which you posted above? You know like closed curves to the outer boundaries. Doing a layered topographic map. I attached an example terrain.

Thanks for any hints and help,

Sebastian

puh I thought I can adjust an old file. But you have much more different cases. The file looks complicated now.

But maybe it is helping you. use mine 3dm

Best Regards

These almost look like 3D printer stripes (printing process layers).
