Hi Volker,

This has come up before on the list ( 
http://public.kitware.com/pipermail/vtkusers/2004-November/077525.html ).

IGES is typical used by CAD applications (with different primitives to 
VTK) so there is a translation problem along with the format reading 
problem.

You could try using AutoDesk's "Mechanical Desktop" to import an IGES 
file and export a STL file. Unfortunately, vtkSTLReader only reads 
triangles and triangle strips though, so polylines and the like will be 
lost.
