This paper presents a high-level tool to build 3D virtual exhibitions from pre-existing 3D models and design virtual visits. Our tool exploits AI techniques and careful interaction design to require minimal technical knowledge by a curator, and allows one to: (i) easily arrange 3D models (e.g. of artworks) in a virtual space;
(ii) find, through an assisted procedure, interesting points of view in the virtual exhibition, and add multimedia information to them; (iii) design virtual visits that connect those points of view to form interactive tours with various levels of navigation assistance for the visitor. Moreover, we show how the tool has been used to build the virtual visit of a church with important Renaissance frescoes
