+The Native IFC page includes the IFC multicore geometry processing preference. Set this value to 0 to disable multicore processing; FreeCAD still creates the IfcOpenShell geometry iterator with one worker so the import can proceed safely. Values above 0 request multiple workers and are clamped before import. This behavior is available in FreeCAD 1.2 and later. See [https://github.com/FreeCAD/FreeCAD/pull/30201 PR #30201].
