The Object Layer Tools allow you to control any layer via any object on that layer. Drawing View retrieves the layer from the object you right-click, then passes it on to the layer tools. If you want to hide an entire layer, just right-click any object on that layer, choose Layer Tools | Off. TPC regenerates the drawing using the new layer settings. Only the layer associated with the object you right-click is affected.
You can accomplish the same things by choosing Edit | Layers, selecting the layer you want to modify then choosing a layer command like On, Freeze or Lock. Right clicking an object on a layer is just more convenient.
Off – Turns this layer off. The objects on this layer are no longer visible but new objects can be added to the layer.
Freeze – Freezes this layer. The objects on this layer are not visible and will not print. Objects on frozen layers are not regenerated which can speed the drawing time.
Lock – Locks this layer. The objects on this layer can not be moved or modified. You can add new objects to a locked layer, but can not modify them once they are drawn.
Unlock – Unlocks this layer. The objects on this layer can again be modified.
Ignore – Ignores this layer. The mouse does not recognize objects on this layer as it passes over them. As a result, objects on this layer will not interfere with nearby objects that are not ignored.
Isolate – Isolates this layer. Makes this layer to the current layer and turns off all other layers.
Current – Makes this layer the current layer.
All Objects BYLAYER – These tools force all of the individual item properties on the layer to what you specify. This overrides the Drawing or Traverse Drawing Settings.
Color All Objects BYLAYER – Set the color of all objects on this layer to BYLAYER. This forces the color of each object on the layer to be controlled by the layer color.
Line Type All Objects BYLAYER – Set the line type of all objects on this layer to BYLAYER. This forces the line type of each object on the layer to be controlled by the layer line type.
Pen Width All Objects BYLAYER – Sets the pen width of all objects on this layer to BYLAYER. This forces the pen width of each object on the layer to be controlled by the layer pen width.
Reset Modified Attributes – Resets the attributes of all objects on this layer to the current Drawing Settings or Traverse Drawing Settings (depending on whether Over-ride Traverse Drawing Settings is enabled or not).
Select All Objects – Unselects any objects currently selected in the drawing then selects all the objects on this layer.
Convert All Objects to Survey – Converts all items on the layer to survey points.
