Type Error when inserting geometry from a loaded file

datamilch

Hi there,
I'm getting a strange TypeError:

TypeError: descriptor 'InsertObject' for 'c4d.documents.BaseDocument' objects doesn't apply to a 'c4d.BaseObject' object

When I print the object I want to insert I get a normal output:

<c4d.BaseObject object called helper - cutplane/Null with ID 5140 at 2616415521856>

The plugin is quite complex at this point, so I try to post only the relevant parts of the code. It's a dialog plugin. Checking for the Main Thread sais True.
Not sure if I made some obvious mistake ...

the file structure:
main.pyp
src-folder ---- helper py

in the helper py there are a few classes, that are simplified in the following code:

class Cutplane:
    ...
    class Helper:
        def load_file(self, filename: str = ''):          
            folder_path  = os.path.dirname(os.path.abspath(__file__))
            file_path    = os.path.join( folder_path, filename )
            loaded_doc = documents.LoadDocument( file_path, c4d.SCENEFILTER_OBJECTS )
            loaded_obj = loaded_doc.GetFirstObject().GetClone()
            c4d.documents.KillDocument(loaded_doc)
            return loaded_obj


        def load_helper(self):
            loaded_obj = self.load_file("helper_cutplane_01.c4d")
            doc = c4d.documents.BaseDocument           
            print(loaded_obj)
            print(c4d.threading.GeIsMainThread())
            doc.InsertObject( loaded_obj )
            c4d.EventAdd()

Hi @datamilch ,

Thank you for a well structured question!

Please check the line:

doc = c4d.documents.BaseDocument

where you assign class type to variable doc instead of the class instance. I assume you meant there

doc = c4d.documents.BaseDocument()

Cheers,
Ilia

@i_mazlov thanks ilia!!!

ok that was truly obvious

actually had to use 'c4d.documents.GetActiveDocument()' to make it work in my case ...
