[vtkusers] vtkSelectPolyData:Can't follow edge

[Green Hedgehog]

Hi all,
I find that several users have mentioned this problem, but no one answered.

->SetLoop(points);

Because of different inputs, every time I get different points as the input
of /Setloop/. However，sometimes it goes well while sometimes results in
ERROR:Can't follow edge. Has anyone got any ideas?
Thanks in advance.

Regards,
Yue
