Select Orthographic View Styles as the View Style Type, then click New Style
. Give the new style a name, and click Properties

On the View Style Properties dialog box, create a filter for the view style. In the Filter Name box, select Create New Filter. The Filter Properties dialog displays. On the Object Type tab, select only the structure slab objects:
