Grasshopper GUID input

[coffsoft (Garry)]

Hello,

I found the code suggestion below, which hints at a solution to obtaining the GUID within GH.

@clement

Once you have the GH component object, you might access the persistent data of it.

e.g. if you have a Brep component which has some breps assigned by the user, you can get Rhino object ids like this:

if component_obj.PersistentDataCount > 0:
    for data in component_obj.PersistentData: 
        if hasattr(data, "ReferenceID"):
            print "ObjectID:", data.ReferenceID

In order to get this code snippet running, it needs one or more namespaces to be imported. I have searched, but cannot determine which namespace(s) are required. I found the page below which is a comprehensive list, but still cannot find GetSingleComponent. PersistentDataCount and hasattrdata are probably in the same namespace. Any help would be appreciated.

Namespaces !

Regards, Garry.
