I better explain to myself I would like to interrupt the blue lines (derived by the solid) to have better legibility of the quota. I did it years ago, but I don't remember the procedure anymore. . .
with the view dependent edit is a little too laborious. I don't remember that it was so complicated to do. it seems to me that it was more similar to the insert -> symbol -> user defined... but maybe I get confused with the gap that is used to break the odds...
