Parameter must be a Guid or string representing a Guid

How do I get centroid of a split surface. 
I even try SurfaceAreaCentroid or SurfaceVolumeCentroid. I get same error

can someone help me...

Hi,

i think splits is your collection (list or array) and you pick one surface called newSurface from your collection. Could be that you should write SurfaceAreaCentroid(newSurface)?

I try SurfaceAreaCentroid(newSurface) . After splitting a surface python is reading as Brep instead of Planar surface. I am not able to use Surface area command in this.

I get error as,

<Rhino.Geometry.Brep object at 0x0000000000000099 [Rhino.Geometry.Brep]>
Runtime error (TypeErrorException): Parameter must be a Guid or string representing a Guid

in attached script I used RhinoCommon script ( I got from Internet user) to get centroid / center point.

But still I need area to calculate at each time. how to calculate area in split geometry?

How can I change Brep object to Surface?

a better version with centroids. check "faceBrep" it has a IspointInside property.

sorry all in c#...

Hello Raul,

I used ghpythonlib.components and loaded to script. This simplified my process
