Align measures

How do I align measures, so that the bars in every system on a page line up? I chose “Fixed number of bars per system” in Layout Options, but as soon as I add notes the bar lines move to adapt. I want them to stay fixed in place.


PS: Sorry if this has been answered before, but a search of “align measures” or “align bars” pulled up nothing

There is no automatic option, to my knowledge. It is sensible that the notes would adjust to fill the space provided by the optimal amount. Assuming you are making some type of exercise sheet or something similar (as this would not be a normal convention in published music to my knowledge) you’ll have to use the note spacing tool in engrave mode. With it switched on, there are larger boxes attached to bar lines. You can move these as you like with alt+arrows.
