Cover fill and object elevation relation

sipofcoffee — Tue, 16 Jun 2026 06:32:55 GMT

Good day, forum,

I am working with imported geo-referenced (3dm) file, which has objects high up above sea level.
In the meantime, I am using a template that has pre structured story levels (they don't match with relative elevations of those imported objects.
The goal of pointing those things is to manage Archicad to show any kind of fill for those imported objects. Currently, most of those imported show none, some of them do in different stories. Can't figure out how Archicad "chooses" on which story to display.

Not sure what kind of information to add since file is too heavy to be shared.
Thank you in advance

Operating system used: Windows 11

Hi,
You did not specify what it is that you want to achieve? You want to see the original cover fills from the imported model?

If so, one unorthodox method would be to open the file 3D view in axonometrical view, from the top (you can choose it from the projection settings) then make a 3D document based on that. You'd have a top projection from your object (assumed it is textured as you wish).

You can also alter the position of the imported mesh to be at project zero, and then set the sea level elevations. It is the recommended workflow. This way you will also have the correct relative elevation but you can also recall the absolute values easily.

hope this makes sense

the imported object plan appearance shoudnt have anything to do with sea level. plan 0 should be project 0, and sea level is the project location setting's height to that level.
if the 3dm to gsm is giving you an incomplete plan appearance, try editing the converted objects 2d script;

project2 3,270,2 will give you an actual overhead projection of the geometry.

Thank you for your response.

I will dig more into 3D documents, because this seems like the most intuitive approach knowing that my imported objects do not match story levels.
Second solution of yours seems a little more complex to someone who has less competence in BIM environment.

I've also updated my post with a sentence of what I seek to achieve.
"The goal of pointing those things is to manage Archicad to show any kind of fill for those imported objects. Currently, most of those imported show none, some of them do in different stories. Can't figure out how Archicad "chooses" on which story to display"

Thank you again

Actually, second solution is "easier" to do than the first one. As Patrick has said too, you can:
1. Move the elevation of your object (from 3DM) to 0.

2. Go to Options -> project preferences - Project Location.
There you can set the altitude (sea level) value to match.
That's it. It won't magically display everything as intended but at least the morph you have won't be floating way above any story level.

My file stores large amount of objects, which might exceed 1000. To my understanding, this means that I have to give such parameter (your method or Patrick's method) to every single objects, because otherwise - they would all acquire same altitude (level), meaning complete destruction of project.

You can go into 3D, select all (ctrl+a, but be wary of hidden layers) and lower everything at once with said value.

Depending on the units you are working in, your model seems to be either at least 43m from project 0 so lowering it will bring it closer to your floor plan cut plane.
