Hi! I launch the same snippet of a code in the Rhino Python Editor and in the gh Python script editor component, for Rhino it works well whereas running it in Grasshopper it returns None. What I do wrong with gh

```auto
import rhinoscriptsyntax as rs
obj_id = rs.GetObject("Object", 8+16, True, True)
rh_obj = rs.coercerhinoobject(obj_id, True, True)
print rh_obj.Attributes

```

You need to change the scriptcontext when targeting the Rhino document from a GHPython script. See this post for a quick example:

> Hi guys. If you want to fiddle with the Rhino document from GHPython, you must explicitly set the script context to target the Rhino document. Here’s one approach: import Rhino as rc import scriptcontext as sc import rhinoscriptsyntax as rs # Set context to Rhino document and disable redraw sc.doc = rc.RhinoDoc.ActiveDoc rs.EnableRedraw(False) # Fiddle with the Rhino document # Set context back to Grasshopper rs.EnableRedraw(True) sc.doc = ghdoc
