Just to verify what I am reading. In Dorico, the clefs in the score and parts will always match with the exception of being able to assign all of any part to a different clef from that in the score. But going back and forth between treble and bass clef in a different way in the score and the part (in the horns, for example. to avoid excessive ledger lines in a C score) is not possible. It’s all or nothing. Is this correct?
I really hope someone says I am way off.
Hi @John_Ruggero,
you can hide the clef in specific layout/s:
Edit:
But what @asherber suggests here below is much more elegant!
Not way off, but also not spot on!
If you select any added clef and look in the Properties panel, you’ll see:

The name is a little confusing, but it basically controls which view the clef will appear in. If you have a clef set to Concert Pitch, then that clef will only show in concert pitch layouts, and not in transposed ones.
Edit: As @Christian_R shows, you can also hide a clef in an entire layout, which might serve your purposes here as well. This would hide the clef, for example, in the score layout, regardless of whether it is concert pitch or transposed.
Ahhh…My faith is restored. Well I was pretty far off and already anticipating various possible workarounds.
I will try both solutions and see which works best for me. Thank you @Christian_R and @asherber for the solutions. I wish I could give both of you “points”.
I’m not sure if it helps, but ottava lines can also be hidden on a Local basis. So you could have this in the score …
… and this in the part:
Thanks @FredGUnn That is good to know.
