After all these years, I still do not understand how to use force duration.
The half note in the example has force duration on it, as soon as I tie it to the preceding eighth note, it all falls apart. Why?
AC/DC shouldn’t be so hard… but then again, “It’s harder than it looks…” 
All the best,

If you really want to use Force Duration, use it left-to-right, i.e. set it on the eighth note. At the moment the eighth ties to the half, the half ceases to exist, it gets incorporated into the eighth. So any properties or otherwise set on the half are similarly “overridden” by the eighth - and if Force Duration isn’t set on the eighth, it’s not set on the new, amalgamated note.
But also, why force yourself (pun intended) to set this for every instance, when there are Note Grouping defaults in Notation Options that handle this for you (or should, if you’re in 4/4?).
You’re right! I overlooked:
“Notes starting after the start of the bar of multiple beats in duration.”
The picture saved me.
I normally do not have problems finding the right options, but this one got away…
Thx!
