Extruding IsoCurves

Hellooo;

Anyone can help me with how to extract isocurves from an organic surface, and be able to extrude them perpendicular to the surface normal to a value controlled by a slider.

Many thanks

Hi Zayad,

this kind of extrusion is called a Fin extrusion in Rhino, but it doesn't exist in Grasshopper. You'll have to do it all yourself.

One solution would be to divide the iso-curves, find the surface normal at every division point and create lines which can then be used to loft your fin.

Thanks David;

I am projecting curves on an organic surface as I want random curves distribution on that surface (dense at an some areas, and spaced out more at another). So with the projected curves, I was able to divide them, but I was not able to get the surface normal at every division point to draw a line there and loft them. As a result, the lofting was not as accurate.

Is there another way to solve this?

thanks
