It would be really a cool feature if it would be possible to define (after selecting the polyline) a vector in which the polyline will be extruded but i understand, that is not easy to implement....

Each point lying on a polyline gets a vector orthogonal to the connection of the next point. Along this vector and a definable value, a volume is extruded from the polyline.

Here of course the question arises, who is the "next" point since a point of a polyline always has 2 "neighbors". Unfortunately, I do not have the answer yet...

So one could, by means of a polyline and another value, filter the point cloud and the view setting would not have to be considered.

Hum, still not sure to understand, especially in which 'dimension' to shift the vertices (because to create a 'volume', you simply need to move the vertices orthogonally to the polyline 'plane', while if you shift the vertices inside this plane, then you end-up with another polyline, not a volume?) ... And also not sure to understand what the goal is.
