Presentation of zones in a Q3DScatter

[Timo_F]

Hey,

I'm visualizing points in a Q3DScatter and now I want to show the zone in the scatter, that presents the possible solution area.
However I'm thinking about a cuboid with eight given 3d corner points that are connected by a line and within that cuboid there should be the 3d points of the solution.
Does anybody have an idea how to solve that or whether it's possible or not?
Is it possible to connect points by a line?

Thanks a lot.

Best regards,
Timo
