The "Labels" tab in the Room Book displays the labels currently available on this eTASK portal, sorted by the level of spatial hierarchy to which they apply.
Label settings always apply to the entire eTASK instance and are created or edited in the Labels dialog. This dialog is accessed via the ribbon.
A preview of the label layer is also integrated into the Labels tab when you hover the mouse pointer over a label. To do this, the label must already be created on the relevant layer. Left-clicking on the layer icon displays the label layer in the model area.
