Increase the number of available Reference Levels

This would make working with multiple split levels, on the same story, easier. I'd set a reference level for each floor slab level.

At the moment, with only 3 reference levels, really only one is available for use, as one is usually set to Sea Level, and another to Project Zero.

Ideally, I'd like to be able to add and remove as many reference levels as I need.

You can have as many levels as you want already so this wish is redundant, but it would seem impractical to go beyond identifying slab levels in most cases.

What would be better in my opinion, would be to be able to turn on and turn off levels based on individual section markers, or insert level lines in sections as needed.

You can have as many stories as you want but only three reference levels.

I vote "essential" for this one. It has beed a long standing wish of mine to not only have more global reference levels but also story related sub-levels. This is an area where ArchiCAD needs to catch up to (or surpass) Revit. The Revit levels, while a bit clunky to use, are way ahead of anything else I have seen.

A few uses off the top of my head:

GLOBAL
- Building height limit
- Multiple ridge & eaves elevations

STORY SUB-LEVELS
- Split level elevations
- Door/window sill/head heights
- Ceiling Plan levels (with associated view option settings)

LINK LEVELS
- Story elevations of hot-linked files

Who voted 'Not Needed'??

Stories are NO substitute for Reference Levels .. you really cannot use them in the same way as it breaks so many things operating across stories .. such as stairs, lifts, etc.

(I think this is actually a problem with some of the tools themselves and how they work with stories - e.g Stairs making the assumption they only ever pass from L1 to L2, not say L1 to L3 bypassing L2 - but fixing that is a much bigger task so leave it for the moment)

Having unlimited reference levels to which you could attach object elevations would be immensely useful such as all the items Matthew listed.

quadruple essential from me

Absolutely essential, if you expect your model to be used for construction purposes.
This inability that AC has to give you more than 2 reference levels is not tolerable. Not being a programmer, I would guess that having more than 2 would not be such a big programing investment, and the benefits would be HUGE.

Essential, plus Elements should at least have the ability to obtain their height values from these Reference Levels, like Top of Wall 300 millimeters below Finished Floor Level of Story. But that's another wish.

What kind of drawings would you want to annotate relative to more than Seal Level, Datum, or Project Zero ?

We have the gravity tool for annotating plan views to any bench mark elevation we want to set. In sections, we can use dimension. I don't know where I would use more that 3 reference levels even if we did have them.

Perhaps it's not for annotaion that you want this. ?

No, it is not for annotation I am talking about but for modelling.
It is kind of like constraints in Revit.

I see. I would vote for that.

For instance:
If you want your model to be useful for construction purposes (and not only for producing design drawings) then you have to model each floor referenced to the structural slab height (everything above slab height belongs to that floor), but you also want to produce drawings referenced to the floor finished height (for instance, the height of the window sills, or the ceiling, are documented relating to the floor finish). So, you have some plan views where you want to show heights of elements of each floor referenced to the structural slab (which is build first) and then you have other elements that have to be referenced to the floor finish height.
That means that you need, at least, a reference level for each floor.

A free number of reference levels would be so great.
Plus the ability to actually reference them from everywhere!
This would make so many things easier.

Could this become part of a bigger clean-up of Reference Levels and Storey Levels. Something that would accommodate more complex buildings - split levels, multi-tower buildings or things like below-grade parking levels that span more than one storey (e.g. a corkscrew ramped structure).

Maybe Storey Levels that are secondary, or levels inherited from hotlinks.

It would be interesting to have traditional floor levels of reference to create plans, and other levels that are only for reference to "jam" construction elements to them, choosing a classification for each level, and choosing whether or not we want to see them in an elevation view.

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.

This one of those "i dont know how we have survived without this" essential wishes, and the single thing i envy from Revit the most (along with groups and the ability to attach elements to other elements)

Multiple reference levels would be a practical solution also for placing associative elevation dimensions in case of hotlinked files. Or maybe I dont know enough about the program yet ?

We are currenlty in the first stages of moving to archicad and generally design projects with multiple blocks. We gather the blocks in one file using hotlink for site plan, elevation and section purposes. Every block has an individual project zero in relation to the sea level and we need to place the dimension levels according to each blocks individual project zero (multiple 0 levels in one section/elevation). Currently we set elevation dimensions origin to user origin for each block separately. But in case of a change in elevation of the blocks, we need to select each blocks dimensions individually and rearrange their relative user origin manually. Defining a reference level for each blocks elevation dimensions origin would speed up this process.

The only thing that graphisoft should do is something as simple as allowing decimal numbers in the floor number, it that would solve most of the reference problems.
