bug in AddSweep2

[raulct00]

Althought I'm giving the rails as a list, a exception is thrown saying: iteration over non-sequence of type Guid
:

Python Code:

for u_cnt in range(len(u_plane)):
            u_splt_srf = rs.SplitBrep(srf, u_plane[u_cnt])
            rs.DeleteObject(u_splt_srf[1])
            u_st = rs.SplitBrep(u_splt_srf[0], u_plane_sec[u_cnt])
            u_crv_s2 = rs.DuplicateEdgeCurves(u_st[1])
            rs.DeleteObject(u_crv_s2[1]) #delete extra curve
            r1 = u_crv_s2[0]  #rail1 curve
            if rs.CurveDirectionsMatch(r1, u_crv_s2[3]):
                rs.ReverseCurve(u_crv_s2[3])
            r2 = u_crv_s2[3] #rail2 curve
            shape = u_crv_s2[3] #shape curve
            rs.AddSweep2([r1, r2], shape)

I have found the solution for the bug, it's problem was AddSweep2 expects 2 lists, so if you input just 1 shape curve, it will fail, even though you might just need one.
You have to create a list out of shape curve(s), even though if you have only one shape curve.
rails = [r1,r2]
shape = [shape_curve]

def extrude_surfaces(self, u_strip, v_strip, mat_thick):
        for u_i in u_strip:
            edg = rs.DuplicateEdgeCurves(u_i)
            rs.DeleteObject(edg[2])
            r1 = edg[3]
            if not rs.CurveDirectionsMatch(r1, edg[0]):
                rs.ReverseCurve(edg[0])
            r2 = edg[0]
            shape = edg[1]
            lst_rail = [r1, r2]
            lst_shape = [shape]
            rs.AddSweep2(lst_rail, lst_shape)
