You can't, as geometry data is automatically converted to pure geometry before it goes into the Script component. The only way to get the guid in is to use a Guid parameter.

But I remember there is a ghx file named "findID" made by  Giulio Piacentino,only he use the old C# script component..

But if you just plug your geometry into a Guid parameter it will find the ID of any referenced object. You do not need any custom code for this.

Hi Bluelotus,

Yes, that component is over 2 year old... Now if you have a Guid it should be as simple as:

if(id != Guid.Empty)

{

var obj = Rhino.RhinoDoc.ActiveDoc.Objects.Find(id);

if(obj != null)

A = obj.Geometry;

}

Written by heart and not tested, but should be more or less like this. Hope this helps,

- Giulio
