Thank you very much for your answer and help KarenMichelle. All stuff i didn't know about and not that easy to find on the net actualy allthough i searched for an answer i had to post this question. But very good and insightfull answer Karen, i didn't know about the orientation adjustments in the scripts and all either, about the doors, windows and other direction objects being locked in the proper direction. That's what the "freeze" button is about i think. Once again thank you very much and you're so sweet !
