there are layers 1..16 in GDL 2D preview, but I cannot use them at all and seemingly the docs about them is quite "compact".
At first it mentions that you can call the separate layers as macros ("A rétegek különösen hasznosak a jelkép részleteinek csoportosítására és ismételt felhasználására (ilyenkor mindegyik réteg makróként viselkedik). Rajzoljon egy ábrát a 2D-s leírás-ablakban a rendelkezésre álló grafikus eszközökkel, majd hivatkozzon erre az ábrára a rétegszámmal a GDL 2D-s leírásban.")
I tried to use it like
call "1"or something but id didn't work.
The GDL Reference Guide doesn't seem to know about it.
Is it work, is there a material about it?
My goal is to have a GDL object that has different visibility on the containing story and the above stories (but to achieve it with only by drawing and not by coding much). Is it possible?
Thx.

You want the FRAGMENT2 command where the 'fragment_index' is the layer number.

One more question:
I control the visibility of the object (a staircase) through GLOB_CSTORY_ELEV and GLOB_HSTORY_ELEV variables in order to show it on some storys (since settings allow only current and current + 1; I would need up to current+2 stories).
Is there a solution not using elevations (that can be affected if story heights change) bur stories?

There used to be buttons to turn the layers on/off but in newer versions they are gone and you must use CTRL+L.

Thanks! I didn`t use this feature before but i am trying to learn the bascis of GDL object making. Where is the origin point/insertion point of the 2D Symbol? Is it the small X dot?
You only need to draw in the fragment layers if you do not want to create code in the 2D script.
You can also minimise the 2D script window and the 2D symbol window so you can see them side by side.
Then you can select and drag what you have drawn in the 2D symbol window across to the 2D script window and it will automatically create the code for you.
Now you can safely delete what is in the 2D symbol window because you have the script for it.

By the way, is it possible to generate a 3D script in the same way?
Edit
I also tried to select and drag it but couldn`t get a code
