I want to create vtk file with mesh(I use vtk 9) The vtk should have :

# vtk DataFile Version 3.0
POINTS 
POLYGONS 
NORMALS

I create a 3d cube object

cube1 = vtk.vtkCubeSource()
cube1.SetXLength(6)
cube1.SetYLength(10)
cube1.SetZLength(4)
cube1.SetCenter(0,2,0)
cube1.Update()

How do I save it in required format? I tried this

 writer = vtk.vtkPolyDataWriter()
 writer.SetInputData(cube1.GetOutput())
 writer.SetFileName('cube1.vtk')
 writer.Update()

I got format 5.1 but I need the old one.If there is any way to get old format?(Except using old version of vtk)

vtk save python

VTK does not allow to select an old format, so VTK 9 can only write legacy files in version 5.1.

In VTK 9 there is support to write in older format 4.2.

writer = vtk.vtkPolyDataWriter()
writer.SetFileVersion(42)
...

This will write in older format.
