Sub-levels that are related and not independent from main levels wold be great.
It's a pain to make everything on structure level and consider this FFL manually on every ceiling, window, non-full height walls...
1 - Relate Slabs to FFL height. (to model screed/ finishes or ceilings)
2 - Relate Window/Door sill to FFL.
3 - Having a global like GLOB_CSTORY_ELEV which could be GLOB_CSTORY_FFL, readable by tags.
4 - Being able to show a second dashed line on sections/ elevations, which would be FFL.
By having such thing as GLOB_CSTORY_FFL we woudn't have to manually input it on every window/ door.
A 2,40 ceiling wouldn't have to be at 2,45 for example. Leaving no margin for errors.
I even did a tag to solve this myself. Native level won't solve most cases.
You can set it with an MVO to solve different views.
