Markus, Bob,

can you confirm this for the latest version of NVIZ - I have this
problem too, it appears to be a bug,
it can get pretty tough to deal with - I had 7 surfaces and wanted to
drape vectors only on a single one
and it always got it back to draping it on all, so after each redraw I
had to switch the drape on the 6 surfaces.

Also when looking at drapingwould it be easy enough to have it drape the
vectors a little bit above the surfce -
it would be invisible but it would ensure that the lines are all visible
(in SG3d it was an option )

thank you

Helena
