Hi,

I know this topic has been discussed many times. I read many of them but as a beginner in Grasshopper I don’t understand the logic behind it.

So what I’ve managed to do was: 1) “imported” the curves from rhino to grasshopper 2) with “Evaluate curve” function I’ve managed to get a point at one end of the curve + tangent at that point 3) I’ve created a plane on that point 4) and on that plane I’ve created a circle (SECTION)

So then I try to make the sweep by connecting the SECTION circles with the curves “imported” to grasshopper. What I get is a complete mess - the sweep geometry goes all around the place.

Can you please point me in the right direction?
