[vtkusers] vtkVRMLImporter question

[allan.martin at utoronto.ca]

Hi all,

I'm pretty new to VTK... I'm trying to import a VRML file that  
describes a surface (of a screw), and then put a box widget around it  
so I can manipulate it.  'vtkVRMLImporter' successfully reads the file  
and renders the screw, but there are 12 actors in the collection.  My  
question: Is there a way to coalesce these 12 actors into one actor?  
(or is there any other way to manipulate the screw as 1 object)

Thanks,

Al Martin
