I have made 3 stories (elevations). in my project.
I have a question - I draw wall in first elevation with hight of 9m (elevations are each 3m) but I can't see it on the second elevation (only as a ghost)
You have to draw the walls on each floor you want them to show up on. They look fine in the model, but the floor plans require the walls to be broken apart. Some tools allow display on different stories, but walls are not one of them.
Following the drawing rule in ArchiCAD you should draw 3m high wall on first story and the same in second and third, like in real construction site. This way you can see your wall on every story and in the model as well.
