Each wall has a title, optional description, and canvas measurements. You place artworks and decos as if building a real wall in a studio: define the space first, then fill it.
You can duplicate a wall to reuse layouts and tweak details—handy for mounting variants or A/B versions of the same wall.
If the wall belongs to a room, visitors see it inside the 3D tour on the edge you assigned; otherwise it remains an independent wall linkable from the exhibition.
