Hi Marco.
I used Max's vSeed as follows.
Turn your edge into a curve by doing copy.
Create a 25 by 25 grid, at a spacing of 1 mm by 1mm, of vectors 1mm long, above your helix, in high z, oriented in the +z direction. Color style the vectors Red.
With no objects selected, Select the color style Blue.
Select the Red vectors, select the curve, and select the helix tube.
Run vSeed.
Apparently vSeed first creates a grid of Blue vectors, intermixed with the Red vectors, with each (undropped) Blue vector being oriented,
so that when dropped, it will be oriented normal to the helix tube at the point on the tube to which it is dropped.
A fraction of a second after the Blue vector grid is created, the Blue vectors drop down to the curve, and are normal to the helix tube.
Anyway, they appear to be normal.
I'm thinking that the blue vectors along the curve would be the targets of orient, but have not got that far, if it is possible with orient without manual picking...
