Selecting Height
When a building component is added to a drawing, its default position is the floor base height, i.e. the level of the floor surface (z-coordinate is 0). If you wish to position the component at another height, you can change its height by using the Select Height function in the auxiliary menu. Select the new locating height in the dialog box.

You can also use the function to display the opaque property of a covering component in a 2D drawing. The overlapping components have different Z coordinate values (Z>0). The component with the greater Z coordinate covers the component with the smaller Z coordinate.
