I just want to make loft by two sets of rectangle.
But as title say, expected IEnumerable[Curve], got list even through I have declared like this. How to fix?

Rectangles are not Curves (or does Python make that conversion automatically?)
base_crvs = [RecListA, RecListB]
is a list of lists. I think the following should work:
recList =  recList.append(RecA.ToNurbsCurve()) recList.append(RecB.ToNurbsCurve()) surface = rg.Brep.CreateFromLoft(recList, start=None, end=None, loftType=0, closed=False)
I modified code but output shows Runtime error (MissingMemberException): ‘Guid’ object has no attribute ‘ToNurbsCurve’
This code means rectangle convert to NurbsCurve right?
Maybe not automatically
As for conversion,
when I changed three points,it works.
first,make input to enter rectangle list.
Second,changed type hint as curve
Third, use rs AddLoftSurf method different to CreateFromLoft
what I want really is realize converting rectangle to curve and loft by the curves in coding.
You have 3 different options:
import rhinoscriptsyntax as rs rec_a = rs.AddRectangle([0,0,0], 10,10) rec_b = rs.AddRectangle([0,0,10],10,10) a = rs.AddLoftSrf([rec_a, rec_b])
from System.Collections.Generic import * import Rhino.Geometry as rg rec_a = rg.Rectangle3d(rg.Plane.WorldXY, 10,10) rec_b = rg.Rectangle3d(rg.Plane(rg.Point3d(0,0,10), rg.Vector3d.ZAxis), 10, 10) curves = List[rg.Curve]([rec_a.ToNurbsCurve(), rec_b.ToNurbsCurve()]) a = rg.Brep.CreateFromLoft(curves, rg.Point3d.Unset, rg.Point3d.Unset, rg.LoftType.Normal, False)
from System.Collections.Generic import * import rhinoscriptsyntax as rs import Rhino.Geometry as rg rec_a = rs.AddRectangle([0,0,0], 10,10) rec_b = rs.AddRectangle([0,0,10],10,10) curves = List[rg.Curve]([rs.coercecurve(rec_a), rs.coercecurve(rec_b)]) a = rg.Brep.CreateFromLoft(curves, rg.Point3d.Unset, rg.Point3d.Unset, rg.LoftType.Normal, False)

Thank you! it works!
curves = List[rg.Curve]([rec_a.ToNurbsCurve(), rec_b.ToNurbsCurve()])
I know what you mean by converting rec_a rec_b to nurbs, but I’d like to know where you learn how to write this.
