Creating a surface from a series of non-planar curves


I have a joined closed curve made up of non-planar curves. I couldn’t create a surface off this with Patch or Loft, and using EdgeSrf after splitting the curve doesn’t work either. Does anyone have any idea on what I could do? Here ( is a link of my file for reference as it’s a little hard to explain clearly, the aforementioned closed curve is under the layer roof!


Hello Cardinia G98,

I selected the curve, ran explode then patch and it appeared to form a trimmed surface.

Thank you,

Hi Andy,

Thanks so much! That seems to work.

Hello Cardinia,

You are welcome. Glad that it worked for you.
