How to access the modelling features on Open building designer (student version)

Hi, I have downloaded Open Buildings Designer - an educational license as I am an Architecture Student. The 2D Drawing works very well however when I change tabs from Drawing the Building Design... All the 3D tools are frosted out and blocked. I can't use any. Was there a way to gain access to 3D on an education license? Or another Bentley software I can download to use 3D?
