Walls
The Wall tool allows the creation of walls which are parametric objects, automatically connected on their vertices and borders. To set the attributes, double-click the Wall Tool icon or select Edit ▸ Settings Window ▸ Wall… to open the Wall Settings dialog.
Walls are host elements, in that certain elements like doors and windows can only be inserted in a wall.
Walls are classified into two families: Standard-case Wall, made of one, uniform component, and Composite Wall, made of different internal components.
