https://community.graphisoft.com/t5/Modeling/Can-not-edit-slab/m-p/267081#M139430 What I can see here - two screenshots. One from Russian ArchiCAD, I guess version before 24, and second from English ArchiCAD 24.<BR /> The first (active, Russian) says - it's load-bearing element (конструктивная функция - несущий элемент).<BR /> Second says that structural load is undefined.<BR /> Also in the second screenshot FLOOR PLAN AND SECTION and MODEL (ОТОБРАЖЕНИЕ НА ПЛАНЕ И В РАЗРЕЗЕ и МОДЕЛЬ) tabs are hidden. It happens when ArchiCAD work environment is switched to "Structural Engineering Basic Profile". Switch to Architectural Basic, Architectural of Structural Engineer profile, to see these tabs.
