    BaseObject.GetAbsPos() returns not the absolute position, it returns the relative.

    import c4d  
    if __name__=='__main__':  
      print op.GetAbsPos()

    GetAbsPos: Returns the absolute position of the object. These will be absolute local coordinates within its parent object.

    This exception is correct. If you want to access the user data object you have to pass the index (starts with 1).

    rd[c4d.ID_USERDATA, 1]

    Well, that doesn't make sense to me. Shouldn the absolute position be the global ?
    As said, it does return the same as GetRelPos() 😪

    rd[c4d.ID_USERDATA, 1]

    Index 700 is the Userdata ? Didn't know that. ;-)

    No, absolute!=global. The C++ documentation contains an article about "Freeze Transformation". It should help you on this topic.

    I also was staggered by this behaviour. I suppose method should be renamed or documented at least (in python docs).

    absolute position = well, the absolute position :)
    relative position = absolute position - frozen position
    frozen position = a position offset

    Yes, I understood that after reading C++ docs. I meant that generally (almost always) game developers use "absolute" prefix to determine that some transformation is relative to global frame, e.g. accumulated traversing scene graph. Python docs doesnt't say that it is the position relative to the parent frame, so I've spent a bit time working this out.
