<<OK I must select lines + surface then make 90° Rotation then Drop then make rotation - 90°
<<Just updated vSeed to version 1.2.
<<Now you can spray points, and then use vSeed.

Sorry
Even with the new seed and with a spray i obtain that!
And same if i select Top , Side, or Same face for give orientation i obtain always vertical lines!


Edit : Curious that works if I offset the face of Cube!



So it is not a "drop" , I must no clone the result ;)
