Documentusertext GH VBScript

Grasshopper
1

Hi all,

i’m trying to find a way in the grasshopper VBScript componant to set and get documentusertext into/from the rhino document.

I’m looking for something similar like the rhino commands “setdocumentusertext” and “getdocumentusertext”

Can someone help me with a small example?

Many thanks!

Hi all,

I found this UserData class and I think this is what I am looking for. The problem is, that I still can’t get a simple example working. What would really help me is if someone has a small example how to set and get a value from rhinos document usertexts with the grasshopper vbscript componant.

Many thanks!

Is there a method for retreiving document_usertext from a file other than the active document?

Hi @dale
How can this be done in Python?

I tried this method:

But this gives me the folowing error:

Runtime error (NotSupportedException): This type of object is not supported in Grasshopper, so this Python script cannot create it. You might want to use ‘scriptcontext.doc = Rhino.RhinoDoc.ActiveDoc’ to use the Rhino doc, instead? If you do, remember to restore it: ‘scriptcontext.doc = ghdoc’.

import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc

sc.doc = Rhino.RhinoDoc.ActiveDoc
a = rs.GetUserText(geo, key)

Thanks @Joseph_Oster the idea worked!

import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc

sc.doc = Rhino.RhinoDoc.ActiveDoc
a = rs.GetDocumentUserText(“test”)
