Propagating the Selection

Create a 3D shape containing a subdivision surface.

1. Select one or more elements.

   If you select a free edge, the propagation is only performed along the free edges. If you select a sharp edge, the propagation is performed along the sharp or free edges.

2. From the Tools Palette, select one of the propagation options:
   
   The cursor position defines either the propagation side when there is an intersection or the propagation direction for faces.
   

   Option	Description
   Linear Propagation	Propagates the selection to a free edge or a sharp edge. Vertex Selection Edge Selection Face Selection
   Loop Propagation	Propagates the selection to the selected element or to a free edge. Vertex Selection Edge Selection Face Selection
   Fill Propagation	Propagates the selection in all directions, to a free edge, or a sharp edge. It is available when you select faces or vertices. Vertex Selection Face Selection

   
   

   When no propagation is active, you can double-click to launch the linear propagation or press Shift + double-click to launch the fill propagation. When a propagation is active, you can do the following: Press Home to move to the next propagation Press Home + Shift to move to the previous propagation Press Home + Alt to move to the next rank Press Home + Alt + Shift to move to the previous rank
