Hello everyone,
In my orchestral score, accidentals overlap with rests in dotted rhythms.
How can I make enough space for both?
This is my first orchestral score in Dorico, so I apologize for any silly questions.
In Engrave mode, what does the system fullness indicator say to the right of this system (percentage in green or red box)? I would guess that it’s over 100%, which means that your system is more full than your various settings allow, and Dorico can’t fit everything in neatly.
I though it was that but the system is 91% full… 
Can you upload your project file here?
Did you use casting off to set a certain number of bars per system?
Ultimately, if things are colliding, then the system is too tight, regardless of the fullness; and you need to add a System Break to reduce the number of bars.
If this is happening everywhere, then you might need to look at the Note Spacing values in Layout Options.
