Layer

The term layers is used for logic layers in the layout model which can be assigned objects. A layer can be used to manage both the visibility and lock of several layers at the same time.

• If a layer is locked, the objects on it can no longer be interactively selected or modified.
  
• When a layer is hidden, the objects contained therein are also no longer visible.
  
  

User interface

The Layer task area displays a list of the existing layers comprising:

• Lock (lock symbol)
  
• Visibility (eye symbol)
  
• Layer designation (name)
  
  

If a layer is selected in the list, the Rename and Delete actions are available.

At the lower margin of the task area, there are switches to control the visibility of

• Transport networks,
  
• Flow relationships (flow arrows),
  
• Dimensions.
  
  

Locking/unlocking a layer

To lock a layer, use the checkbox in front of the layer name in the Lock column. If the tick in the checkbox is set, the corresponding layer is locked.

Hiding/unhiding a layer

To hide or unhide a layer, use the checkbox in front of the layer name in the Visibility (eye) column. If the tick in the checkbox is set, the corresponding layer is visible.
