Allplan Forum: How to export IFC 2x3 with the pythonscript API ?

Hi!
I checked the new documentation and example for exporting/importing ifc files, but it only seems to work with the IFC4 version not with the IFC2x3.

I tried the example addon here:
…\etc\Examples\PythonParts\BasisExamples\ExportImport\IfcExportImport.pyp
…\etc\PythonPartsExampleScripts\BasisExamples\ExportImport\IfcExportImport.py

When I select the wanted version with a default 2x3 translator file and press execute nothing happens, not even a new line in the Trace window.

When I try to save ifc4 it works fine but I really need 2x3.
Any suggestions ?

doc here:

Hi,

According to the doc, IFC2x3 is correctly supported.

In the py file IFC4 is forced :

build_ele.IfcExportTheme.value = AllplanSettings.AllplanPaths.GetEtcPath() + r"Favoriten Standard\IFC\Ifc_4_standard_export_DEU.nth"

I've already tried changing that hardcoded file to a proper 2x3 .nth file still nothing happens.

It's working if you force the right nth file in the script but keep ifc4 in the palette :

build_ele.IfcExportTheme.value = AllplanSettings.AllplanPaths.GetEtcPath() + r"Favoriten Standard\IFC\Ifc_2x3_Coordination_View_eng.nth"

I selected ifc version 4 and used AllplanSettings.AllplanPaths.GetEtcPath() + r"Favorites - standard\IFC\Ifc_2x3_Coordination_View_eng.nth"

but the resulted file still was in ifc4

Did you check your exported file ?
Open the ifc file in a text editor and in the first few line there is a line : FILE_SCHEMA(('IFC4'));

So even that I forced the 2x3.nth file it still saved ifc4.

Thanks in advance

IFC2x3 here.

I don't like to force certain parameters in this way, it's a source of errors...

I hope the script will be updated and reposted soon.

Tried the same thing as you, still couldn't save 2x3. I'm trying to reinstall allplan now, maybe that can solve the difference

After reinstallation the problem still persists
( in older versions of AllPlan with the drawingservice I could save ifc2x3 by changing the version to ifc 4 and selected a 2x3 translator but not with the new ExportImportService )

Anyone have any other suggestions ?

I even tried all the versions with a for loop, but only ifc4 versions were saved check attached images.:
