Scripting rail styles

Scripting
1

When using the graphical interface, it is possible to select styles for rail in Sweep1 (for instance “Roadlike Top”)
In RhinoScript, rs.AddSweep1() does not allow that style option.
I tried to add it, but without success.
Any hint about how to implement that style option successfully ?
Thanks !

@cyl,

it seems the rs.AddSweep1 method is not complete. As a workaround you can use RhinoCommon, here is the example script from the docs:

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext

def Sweep1():
    rail = rs.GetObject("Select rail curve", rs.filter.curve)
    rail_crv = rs.coercecurve(rail)
    if not rail_crv: return
    
    cross_sections = rs.GetObjects("Select cross sections", rs.filter.curve)
    if not cross_sections: return
    cross_sections = [rs.coercecurve(crv) for crv in cross_sections]
    
    sweep = Rhino.Geometry.SweepOneRail()
    sweep.AngleToleranceRadians = scriptcontext.doc.ModelAngleToleranceRadians
    sweep.ClosedSweep = False
    sweep.SweepTolerance = scriptcontext.doc.ModelAbsoluteTolerance
    sweep.SetToRoadlikeTop()
    breps = sweep.PerformSweep(rail_crv, cross_sections)
    for brep in breps: scriptcontext.doc.Objects.AddBrep(brep)
    scriptcontext.doc.Views.Redraw()
    
if __name__ == "__main__":
    Sweep1()

c.

@clement
Many thanks for your help !
Not only it works nicely, but this is for me a good example of RhinoCommon use.
