How to avoid high column of earth when using real RL's in models

[KeesW]

I prefer using real RL's for floor levels (as recommended by Graphisoft) and am modelling a house on a steeply sloping site with ground level about 180m above sea level. External 3D models therefore default with 180m high columns of earth under the ground floor. Just as well I am not building on top of Mt Everest!

I can avoid this by modelling with nominal levels - say ground floor at 5m (to allow for the slope). Archicad examples conveniently model their examples on flat, or nearly flat, sites floating near sea level which entirely avoids this issue. Is there a way to use real RL's on high sites without generating this problem?

Recommended by Graphisoft? Then what is the point of the Sea Level input on the Project Location page...?

I don't know. You tell me. What are the relationships between Project Zero and Sea Level and ADL?

Try just adjusting the skirt height of your mesh.

It can also be dragged in 3D with the height option in the pet palette.

In your case Project Zero & Sea Level are the same. I usually have Project Zero be my ground floor slab or a chosen datum point on the site.

ADL? Traffic?

See this Poster....

BTW I have to report that coordinate OBJECTS 24 report the same values for height with either selection of showing value based on Altidude or Project Zero. This is wrong. The values when we select from project zero should be relative to altitude. So if altitude 15 and we have a level at sixteen meters the values should be 16 m from sea level and 1m from Project zero.

Can you upload your screenshots again? Currently, they are so small I can not discern any text in it.

So, this is in Archicad 24?

Hi Lazlo, can you try to save locally? if still is unreadable can I send as PDF? the image has size 2000x4000 px.

Here Pdf.

Project zero is the base level for the project. Its actual starting position in space. The zero level position in Archicad.

Sea level and Altitude (<toAltvalue>) are relative levels which don't change the position of the model in space but allow level annotation to reflect these references.

Altitude (Sea Level) is set in the Work Environment under Project Location (see below)

Thats the good news.
Unfortunately.....

1) Altitude can only be set in meters, which is NOT Australian Standard for Levels.

2) And this is the killer......

These settings cannot be used as the default when placing levels using the Level Dim Tool. So when placing a spot level using the Level Dim tool the Text part must be selected after placement, the setting changed to Custom Value and <toAltvalue> selected. Its makes this method unworkable. A medium site model my have 100+ spot levels and to select these manually to show the correct level is not practical.
