rhino to grasshopper3d

Hi,

I'm new with gI have a rhino script which i need to convert it to grasshopper3d. but I didnt figure out how to do it. Could any one help me please.

id = rs.FirstObject(True)
a = Rhino.RhinoApp.RunScript("_ExtractPt", False);
pids = rs.ObjectsByType(1)
if(len(pids)):
i = 0
xa = []
ya = []
for pid in pids:
x,y,z = rs.PointCoordinates(pid)
xa.append(x)
ya.append(y)

Thank you very much in advance.

Hi a4411252,

rs.FirstObject function does not work with grasshopper document. Instead you will have to assign the desired geometry (from which you want to extract your points) manually.

The attached grasshopper file supports four type of geometry: curves, surfaces, polysurfaces, meshes.

If there's something you do not understand in the file, the best thing would by to first start reading Grasshopper Primer. It will explain the very basics of Grasshopper.
