[vtkusers] Re: Scale bar question

[Steve Joyce]

When I've used it in the past it has zoomed with the 3D actors.
I think it is one of those objects that is part 2D and part 3D.

I tried that but it's a 2D object not a 3D object so its not part of
the
scene and hence it just overlays the 3D actors. ie. Doesn't change
when
I zoom etc

Thanks Paul
