Invalid 3d and 2d symbol: Windows

[alzbetano_]

Hi everyone,

I have downloaded Velfac window GSM models and added them as objects to my Archicad library.

However, after opening the objects, the 3D and 2D symbols seem to be invalid, and I can't use them in my project.

Does anyone have any idea what could be causing this issue and how it can be resolved? Could it be that the windows work only in a different version of Archicad?

Thanks!

Operating system used: Mac Apple Silicon

Perhaps I have the same problem?

I have opened a studio model in AC28P, and have lost my doors and windows.

Source model in AC27

AC 28 model

In the IFC Project Manager I can no longer visualise an element , nor when I export IFC no doors and windows

All issues with version 28 should be discussed in the Technology Preview forum ...
