Selection Filter in Freestyle
With selection filters, you can filter the type of mesh elements, such as faces, edges, and vertices, and shapes to create Freestyle surfaces. The selection filter is on the status bar of the Freestyle Modeling environment. The default filter type selects all the mesh elements. When you select a filter, mesh elements of only that filter type are selected or highlighted. To select all the mesh elements of that filter type at the same time, enclose your mesh elements in a selection box or select elements of that filter type one by one.
