Error when creating a default project structure

[balrobs]

Don't know if it's me missing the right workflow or if it's a bug:

1. with latest BIM-addon and NativeIFC-addon create a new empty project
2. activate BIM-addon
3. from the menu select 3D/BIM->Project
4. close dialog with Yes (should create a default structure: IfcProject->IfcSite->IfcBuilding->IfcBuildingStorey)
5. this is what I see in the tree view:
6. and these are the errors in the report view:

   
   Traceback (most recent call last):

   exportIFC.ifcbin = exportIFCHelper.recycler(ifcfile, template=False)

recycler.init() got an unexpected keyword argument 'template'

You need a more recent version of FreeCAD unfortunately... In 5276114 I added a better error message. Unfortunately that's all I could do for now, as this currently uses the Arch IFC exporter. Later on we'll recode that entirely and depend only on IfcOpenShell, that should avoid this kind of problems.

A new release of FreeCAD is coming soon, otherwise you can simply replace your Arch/exportIFCHelper.py with this one: https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Arch/exportIFCHelper.py
