IFC export workaround and question

[thomas-neemann]

...

I deleted the output window before the export, so the messages should be complete.

how do I know which part it stops at?

[bernd]

you need to activate debug messages ... This is how it looks for me. In report console It is printed on which object the exporter stops ...

you might missed the debug messages because they seam to be activated on import even for export ...

selekiere doch mal nur das objekt "BldgPart__GF_WinDoor" und versuche einen Export. Das ist ein Architekturobjekt BuildinPart (ist ein container) Fals der Fehler kommt, kannst Du ein FreeCAD datei erstellen mit nur dem Objekt speichern öffnen und wieder exportieren, wenn Fehler die FreeCAD datei hier posten.

Ha ich habe etwas gesehen ... Stelle mal in Arch auf Ifc2x3 um ... dann geht es. Wenn ich auf IFC4 umstelle kann ich reproduzieren ... Starte FreeCAD neu damit diese Einstellung sicher übernommen wird. Diese braucht ein Modulreload

sorry ... German ...

Switch to Ifc2x3 in Arch settings and restart FreeCAD because this setting needs a module reload. If I switch to IFC4 I can reproduce the problem.

[bernd]

here we are ... a small FreeCAD file of only one object ... this is needed to debug the problem ...

I was able to rebuild it from scratch ... a building part with a box and the type of the building part set to undefined results in export break because the method createProduct breaks in ifcopenshell.

same happens on a floor or building object if the type is set to "undefined" (actually they will switch to a building part object because of this setting) but it does not happen if the type of a structure or a wall is set to undefined.
