I’m a MArch student and I’m very new to GH. I’m trying to make a paramentric object but this error came up and I couldnt figure out why. I was trying to convert these contours into surfaces so I could extrude them. I have attached my rhino file and GH. Much appreciated to anyone would help and thanks in advance!!
the error comes from the Curves not being Closed: it’s impossible to generate a Planar Surface from an open curve
in particular you can see the first and last curves are open:
