The Global Archicad Community

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.

[Steve Jepson]

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. ?

[LaszloNagy]

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

[Steve Jepson]

I see. I would vote for that.
