This tool allows you to "walk" up and down the layer list, displaying one layer at a time. As the layer number is advanced (either forward or backward), the previously displayed layers are turned off. This provides an aid to understanding the part's contents. The previous layer settings are restored upon closing of the dialog.
Lists all the layers that contain objects. The currently active and visible layer is selected. The active layer can be changed by selecting a different layer in the list.
This area of the dialog will probably where the most time is spent and contains controls to easily step through the layers in sequence.
Makes the lowest layer with objects the currently active layer.
Decreases the currently active layer to the previous layer with objects.
Increases the current active layer to the next layer with objects.
Makes the currently active layer the highest layer with objects.
When option is on, a Fit View is done whenever the active layer is changed.
