Hi Arno
sorry for the trouble. According your suggestion I tried to see guid number in the object created by Library Creator, but I was not able to see any guid number. I tried to see guid number of the object displaied by SDK object placer but also in this case I was not able to see any guid.
Where I can find such devil guid?
In the library creator tool, open any library, and in the tools tab, click on the "create Guid listing" you will get a .txt file with the list of the objects Guid.

In library creator XML you can click the plus next to the model name, that will show more details including the guid.

Or exporting the guids as txt as suggested also works, but is one extra step.
