This method allows a render content hierarchy to be edited using a modal (AKA 'pop-up') editor.
If the original render content is in a document, it will remain there, and the edited one will be
'free-floating'. Therefore it is the caller's responsibility to do any replacement in the document
if required. The returned new content will be owned by the caller.
RhinoCommon (in RhinoCommon.dll)
public RenderContent Edit()
Public Function Edit As RenderContent
Returns an edited version of the content hierarchy if successful, else null.
The method always edits the entire hierarchy. It places a copy of the hierarchy in the editor
and selects the copied item that corresponds to this one. Therefore, editing a child will return
a top-level render content, not a child.
