I just tried some dimension in R2024 and all seemed fine (coming from R2023). i did face to face, and face to core etc.
Tabbing also works for me. Even when I set the alignment to "face", I can tab to the core and so on. I never noticed problems in earlier versions, but R2024 seems very refined so far.
Can you explain better what the struggle is?
I'm currently building an existing building, so I'm not dimensioning a lot and may not have come across your problem yet.
