Closed Sweep by Closed Curve In Grasshopper

Hi There,

I am trying to sweep a closed curve profile on a closed rectangle as you can see in the attachments. But Grasshopper gives errors and the result never was what i wanted to be.

Can you help me out?

Thanks alot really.

Can you explain the logic of this? Why are we adding seam and intersection?

In GH, you would highly likely get your sweep working if you place your profile curve’s starting point on the rail curve’s starting point.
