Hello,everyone, Recentaly I using displayconduit draw an Sunpath Diagram(show as picture 1). in Rhino。and the print preview is the same as display in viewport. but when I print the sunpath diagram as vector file,the print preview(picture 2) is ok,however the output is different form the viewport one, the sunpath blow the clippingPlane has been printed(picture 3), it is an bug on print or displayConduit?

    def PostDrawObjects(self, e):
        e.Display.AddClippingPlane(Point3d.Origin,Vector3d.ZAxis)
        self.DrawCoordinate(e.Display,Color.Black)
        self.DrawSunPosition(e.Display,Color.Yellow)
        self.DrawSunPath(e.Display,Color.Purple)
        self.DrawDateTime(e.Display,Color.Red)
        self.DrawSunPathCollect(e.Display,Color.LightGray)
        self.DrawSunPathAtSameTimeInDifferentDay(e.Display,Color.LightGray)

PS. print as raster is OK
