To Control Individual View Display Using Layers
You can change the display status of model layers within a drawing without changing the part or assembly in which that item was created.
You can force a drawing to completely ignore the layer status in its model when determining if it should display an item on a layer. Creo Parametric displays all items on model layers in the drawing, and you can manipulate the items separately at the drawing level. You can blank or display layers at the drawing level without making changes to the part or assembly in which the item was created, and the model does not change.
To set a drawing so that it ignores the layer status of its model, do one of the following:
On the View tab, click Layers. The Layer Tree appears. On the Layer Tree, click Settings > Drawing Layer Status. The Layer Status Control dialog box opens. Select the Ignore display status of layers in the model box.
Set the Detail option ignore_model_layer_status to yes (the default value). If you set this option to no, the drawing layer status follows that of the model. If you set this option to all, the drawing ignores the status of all model layers, including high-level layers with special designation, such as Hidden Items, Shown Items, PIPING_BLANKED_LAYER, and so on.
After you separate the drawing layer from the model layer you can specify independent view display, which takes precedence over the main drawing for that view. Then:
When you create an independent view, the layer display defaults to that of the main drawing.
When you create a detailed view, the layer display defaults to that of the parent view.
You can then modify the display for any view independently, or reset it to follow the drawing display.
You can copy the display status for the drawing or a view to any other view or the drawing, and then modify the display individually for each.
 
* You can control the display of datum curves in the shaded view of a drawing only through the model or assembly layer tree.
