[vtkusers] writing and reading with vtk

[Jérôme]

Hi,
I just looked at your file: It seems that you have an empty PointData field,
as well as empty CellData. If you delete these XML elements (PointData and
CellData), your geometry is successfully read (sort of 3 merged boxes, isn't
it?)

My advice is to check how your data are written.

'Hope that helps,
Jerome
