CreateCircumscribedPolygon returns points!

[seghierkhaled]

Hello, i try to create polygon with Rhino.Geometry.CreateCircumscribedPolygon
In the help : CreateCircumscribedPolygon(circle: Circle, sideCount: int) -> Polyline,
but the result are points why?

[AndersDeleuran]

Polyline output wanted but got a list of points

You probably want the PolylineCurve class, alternatively call the ToNurbsCurve() method on the Polyline. The reason a single Polyline will output as a list of points, is that it is essentially what it is (it inherits from the Point3D list class) and the GHPython component will see it as an iterable and try to get/output its values (ie the points).

Thanks , are they mean list of points by polyline term in the help?

@seghierkhaled,

A Polyline is just a list of points.

If you need a curve, call Polyline.ToPolylineCurve.

Thank you , yes that what i did , the term Polyline made me confused

It is more than just a list of points. In that it has more (super duper useful/overlooked) methods, such as:

• CreateInscribedPolygon
• CenterPoint
• BreakAtAngles
• GetSegments
• PointAt
• ClosestPoint
• TriangulateClosedPolyline
• DeleteShortSegments
• MergeColinearSegments

It just inherits from Point3dList, as Dale points out.
