Label object to use Sea Level

[Graeme]

I have a Label object that has an option to display the height a slab is at relative to Project Zero or the Current Storey. I would like to add the option of using the "Sea Level" level but I'm not finding it in the Manual.

Am I right in saying what I'm wanting to do is not available via GDL?

Operating system used: Windows 11 25H2 26200.7840

There is a global called "GLOB_PROJECT_ALTITUDE", but you'll most likely need to request "Reference_Level_Data".

The forth item will be the sea level in relation (!) to project zero. (easy way of introducing a sign error here ;))

Yes.

n = REQUEST ("REFERENCE_LEVEL_DATA", "", name1, elev1, name2, elev2,
name3, elev3, name4, elev4)

This will give you the elevation of all 4 reference levels.

Or you can just use an autotext label.
