Seam line Adjustment of Lofted Surface

Hi,
How would one adjust the position of the seam line of a cylindrical lofted surface?

Loft follows the curves. Adjust the curve seams. http://developer.rhino3d.com/api/RhinoCommonWin/html/M_Rhino_Geometry_Curve_ChangeClosedCurveSeam.htm

If it’s a cylinder, I’d rotate it. If it’s a loft, I’d adjust the seams of the input curves. I do not know if there’s anything in RhinoCommon for adjusting the seams on surfaces. Can’t find anything searching for it.

Thanks. It’s a loft and I’m working in grasshopper solely.

the real problem I have relates to the “To Polar” Component.

By default the Phi output is_“Planar angle in radians counter-clockwise starting at the plane X-axis”_

Can I adjust this start position?

At present, I have to adjust the input curves inputted to this component and then readjust to get them back to their original position.

You are getting scripting answers because you tagged this as grasshopper developer. Tag should be Grasshopper.

Can I adjust this start position?

No one knows until you post some files for us to see the situation.

Good call, I changed the category.
