I suspect that object is from ArchiTerra - they had a rudiiiimentary library done in GDL back in the old days
I'm sorry to to contradict you but this is not the true!
The ArchiTerra library (as the software itself) is always update in order to be compatible with the latest ArchiCAD version.
Actually it is downloadable from the Object Depository and it works fine (just look at the number of dowloads!).
That object ""traliccio alta tensione" was a library part coming from the very first ArchiCAD version and it hasn't been update because nobody asked anymore for it.
I kindly suggest that user to contact the Cigraph Tech Support that will help him on this issue...
