FBX export issue

[Ahmed_K]

The previous datasmith fbx exporter create clean geometry, the actual FBX exporter triangulates all faces, 

Any solution to have clean geometry , it's impossible to work with such model in 3ds max.

Operating system used: Windows 11

Is this with the native FBX exporter, which I think was added in AC28, or a 3rd party one such as the one previously supplied by Epic for TM? Also, what do you mean by "datasmith fbx"? They are two different formats...

[Ahmed_K]

the screenshot shows the result of the native FBX format from Archicad 27.

since Archicad 24 , the old FBX ecporter provided by epicgames is not available, that exported creates clean geometry , 

the fbx exporter for Archicad 27 create triangulated geometry.

Is the geometry of an imported FBX editable? Could you try apply a quadrangulate modifier to your imported model?

[Ahmed_K]

yes , it's an editable mesh , quandrangulate modifier did not remove triangulation.
