Hi, I am trying to lofting surfaces from GHpython. I’ve tried both rs.AddLoftSrf() and rg.Brep.CreateFromLoft() methods. The script run successfully but none of the surfaces are showing up in the space. Please see below screenshot and script. Please help if anyone knows why.

HI YinglinW
The AddLoftSrf() function return a list，So you need to write MySrfA.append(a[0]) like this.
