Converting them to 3d objects is a good idea. Here is my file:
http://rpi.edu/~doriad/Paraview_List/lines.vtp

When I run a glyph filter, it seems to want to glyph the normals, not the
points. If I change it to "sphere", the desired result is obtained, but that
seems a bit wacky. Shouldn't I be able to select "Points" somewhere?

When I run the tube filter I get a bunch of these:

 Bad normal s = 0.433013 0.75 0.5 n = 0 0 0

Could not generate points!

I'm not familiar with the tube filter - is there something else I need to
do?

Thanks,

David
