Managing Applied Labels
You have access to the list of labels of a surface, of which you can modify the order, the transformation and the name.
This function is available via the contextual menu of the selected surface. Right-click on the surface then select surface, Edit the properties, and then select the Label tag.
Tip
To click on a surface, the surface must be visible. Display all surfaces by right-clicking within the viewport and choosing the option, Show All (Ctrl+Shift+R)
The label placed at the top of the list in the Labels manager is the one perceived in the foreground in the active view.
The up and down arrows 
allow you to change the layer order of the labels. Select the label and click on the arrows according to the desired arrangement.
You have the possibility of renaming the labels by entering a new name in the input field located at the bottom of the Labels zone.
The U and V Offset and the Rotation parameters of the Transformation zone allow the label to be placed more precisely by entering numerical values directly or by using the keyboard cursor arrows.
