Thank you for the reply. Although the simple test does not recreate the situation. In simple situation it works (that's why I used this method to extract points of interest positions from a model). In any case, I gave up on this approach not just due to technical aspects, but as conceptually not appropriated in my case.

RE: Absolute coordinate for entities
Yes, this is correct - I am extracting the model.dae from KMZ file and parse the model.dae for nodes that are instances of specific components and taking their coordinates - creating placemarks which are relative to the model GIS coordinate (taking into account the transformation from GIS to Cartesian, offset and translating back). However, what I figured out - the coordinate of the node is not relative to origin of the model but to some other point in the model - so my question - how can I calculate/get the absolute coordinate (relative to origin of the model).

Absolute coordinate for entities
I am exporting model to KMZ. I am reading Collada file model to get some entities for particular component to be presented as placemarks in Google Earth. My problem that coordinates that I am getting on the node are not relative to the model origin but to somewhere else. Can anybody help me to find a way to calculate coordinates relative to model origin (which is placed as GIS coordinate)? What is the algorithm?
