I recently purchased The Courtroom from this series. I need some help with assembling this courtroom set. How do i know which wall goes where? Do i need to increase the prop sizes? How do I keep it uniform? The ceiling appears to be upside down when i click on it. How is interior lighting used. I know I can go to Display and shut off all the shadows. Is it best to use drag and drop or should I push the arrow for characters and props? How do i animate the door to open/close. I can't find any tutorials to help me and I have searched through the Forum Discussion. Thanks for any help.
