Maybe somebody knows how to do it without having to separate the elements in different layers or editing their intersection number ?
Thanks!
The line will show up in the 3D window if you turn Contours on.
Layers / intersection number is the typical way to accomplish this for sections/elevations/3D Documents. The "old fashioned" way that will work for you is to make a duplicate of the material assigned to the adjacent elements and assign one of those elements the duplicate material. When like materials abut each other, ArchiCAD removes the line - this is generally desired in Elevations where walls fit together. But you can force the lines to be visible by assigning a different material, even if it is an exact duplicate. The contour line will NOT show up in a rendering though.
