Angle between planes

Hi all,
I would like to quantify an angle between 2 planes.
Q3DC allows drawing lines, not planes.
Do you know how to get this parameter?

Thanks a lot,

You can use this code snippet to get angle between two planes. You can put it into a scripted module if you want to avoid copy-pasting code, but often what happens is that you add markups to your scene (mark points, lines, planes, etc.) and then run a script that computes all metrics (angles, distances, etc.) that you need by a single click.

Thanks @lassoan .
So the first plane in the list is the “reference”?
I would avoid computing the complementary angle (or at least I would know if I’m doing it).
