Hello,
I want to paint the objects that meet the criterion
object = polyline
criterion = if smaller than 700 meters
however I got stuck in the list part … I always get confused in lists

Try Filter by bool mask.
What do you mean by paint?
bool máscara deu certo
mudei as cores das polilinha com comprimento menores que 700 metros
