Several fuslage python bindings seem to be broken

[hardt-fa-flb]

I tried to access the fuselage skin segments with python. Unfortunately, I got stuck by walking through the class hierarchy at the CPACSFuselageStructure.get_skin method, that returns an empty object. The output of the script below is:

['__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__int__', '__le__', '__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'acquire', 'append', 'disown', 'next', 'own'].

Use case here: fuselage.zip

from __future__ import print_function

from tixi3 import tixi3wrapper
from tigl3 import tigl3wrapper
import tigl3.configuration
import os


def display_fuselage_structure(tigl_handle):
    """
    This is an example how to use the internal tigl/pyocc API
    to display all wing and fuselage segments
    """
    # get the configuration manager
    mgr = tigl3.configuration.CCPACSConfigurationManager_get_instance()

    # get the CPACS configuration, defined by the tigl handle
    # we need to access the underlying tigl handle (that is used in the C/C++ API)
    config = mgr.get_configuration(tigl_handle._handle.value)
    uid_manager = config.get_uidmanager()

    f1 = uid_manager.get_geometric_component("Fuselage")

    structure = f1.get_structure()
    skin = structure.get_skin()  # Funktioniert nicht

    print(dir(skin))


if __name__ == '__main__':
    tixi_h = tixi3wrapper.Tixi3()
    tigl_h = tigl3wrapper.Tigl3()

    dir_path = os.path.dirname(os.path.realpath(__file__))
    tixi_h.open(dir_path + "/fuselage_structure-v3.xml")
    tigl_h.open(tixi_h, "")

    display_fuselage_structure(tigl_h)

The class is probably just not properly registered in the configuration files for the Python bindings with swig. Thanks for letting us know! We will check it out.

List of broken python bindings:

• CCPACSFuselageStructure.GetSkin(), and all other boost::optional bindings
• CCPACSSkin.GetSkinSegments()
• CPACSSkinSegments.GetSkinSegments()
• CCPACSSkinSegment.GetGeometry(), via CTiglStringerFrameBorderedObject, which is ignored in the SWIG config

The boost::optional bindings bug includes also all fuselage structure components like frames, stringers, doors, walls, ....
