Levels/Layers Options
The Levels/Layers Tab is used to customize the stack level or layer an object is contained in. To set
layers for objects, select the objects on the oneline diagram (edit mode only) and then choose . The
Levels/Layers Options page of the Format Multiple Objects dialog will be displayed, with the following
settings available.
Stack Level
An object’s stack level dictates what objects it will appear above, and which objects it will appear
below on a oneline diagram. For example, circuit breaker and pie chart objects have a default stack
level of Top. Therefore anything with a stack level of Middle, Background or Base will appear
underneath pie charts and circuit breakers on the oneline diagram. Objects that are within the same
stack level and are drawn in the same location will result in the last object drawn being the visible
object on the diagram. You can toggle which elements within the same stack level at the same
location is visible using the Send to Back and Bring to Front buttons in the Formatting ribbon group
on the Draw ribbon tab.
Layers
Layers are different than stack levels in that layers are designed to allow the user to filter the
elements visible on a diagram (in run mode). Initially all diagram objects are in the same layer,
called Default. This default layer cannot be modified or deleted. However, you can introduce
additional layers using either the Add New… or Define… buttons. Clicking on Add New… will
open a dialog to name the new layer, and will automatically add the new layer to the case and
change the Layer name in the drop down list to the new layer. Clicking on Define… will open the
Screen Layers list display, which will allow you to manage the full list of layers defined for the
diagram. Once layers have been defined, you can choose which layer the selected objects belong to
by choosing the Layer name from the drop-down list by clicking on the down arrow to the right of
the layer name.
Settings for resizing when zooming
You can modify the maximum and minimum zoom levels at which the selected text fields will no
longer resize. Thus when zooming in or out on the diagram, text fields will resize according to the
zoom level until the minimum or maximum zoom level are reached. At that point, text fields will no
longer resize, but will stay fixed at their current size as you continue to zoom.
Maintain Fixed Screen Location (do not pan)
This option is available for text fields. When checked for selected text fields, these text fields will no
longer pan when you pan the rest of the diagram. This allows you to place text that will always be
visible, regardless of what part of the diagram you are observing. You can still move the individual
text field itself in edit mode.
Maintain Fixed Screen Size (do not resize on zoom)
This option is available for text fields. When checked for selected text fields, these text fields will no
longer resize when the zoom level of the diagram is changed. This allows you to place text that will
always be visible at a constant size, regardless of what zoom level you are currently observing on
the oneline diagram. You can still select the text fields themselves in edit mode and change their
font size.
