Hi , I am new using dorico I come from musescore, I am trying to write something like this
nevertheless I cant find the option to hide the mesure lines or add more tempos for just one specific mesure. The official online instructions don’t work. They tell me to use the H key, but it doesn’t work, or to use ctrl 0, and it doesn’t work either. I am using dorico SE I really appreciate your attention and response.
Hi @pianofortetrompeta, and welcome to the Forum and to Dorico!.
you can use hidden tuplets and cue sized notes for this. I will prepare an example and post it here in short time.

Meanwhile @claude_g_lapalme has courteously responded. 
As an add-on I share a file with two possibilities for the first bar of your screenshot:
A: using hidden tuplets (in my example the numbers are not hidden jet).
The playback will not be optimal with this method though, because of the many notes in the 6 beats.
B: using open meter (and without needing tuplets). You can then hide the returning 6/4.
The advantage of this method is that the playback is much better, and you may want to add some gradual tempo (accelerando).
