            Select an edge loop
          
       
       
       
       
      
      An edge loop is
         a path of polygon edges that are connected in sequence by their
         shared vertices. For example, if you select one horizontal edge
         on a sphere, an edge loop selection will attempt to select all of
         the horizontal edges along that same line of latitude on the sphere.
      
      Edge loop selections let you select several
         edges across a polygon mesh without having to select each edge individually.
      
      There are several options for selecting an edge
         loop on a polygonal mesh in Maya. You can select:
      
      
         - an
            edge loop that fully traverses a polygonal mesh
         
- an
            edge loop that partially traverses a polygonal mesh
         
- a multi-directional
            edge loop path on a polygonal mesh
         
For more information on how an edge loop selection
         works, see 
                  Edge ring and edge loop selection tips.
      
      To
         select an edge loop that fully traverses a polygonal mesh
      
      
         - In
            the scene view, press the right mouse button over a polygon mesh
            and select Edge from the context sensitive marking menu.
         
- Double-click
            on an edge of the polygon mesh where you want the edge loop selection
            to occur.
            When you double-click an edge on the mesh, a
               path of selected edges appears across the mesh in either direction
               from the edge you select.
             For example, if you double-click on a single
               horizontal edge on a sphere, a loop selection will select the remaining
               edges that lie along the same line of latitude on the sphere as
               the edge you selected, provided the selection does not encounter
               any faces that are not four-sided.
             
To select a partial edge loop
      
      
         - In
            the scene view, select the polygon mesh upon which you want to select the
            edge loop.
            The selected polygon mesh highlights in a green color.
             
- From
            the Polygons menu set, choose 
                     Select > Select Edge Loop Tool.
            The selected polygon mesh highlights in a blue color
               to indicate edge selection mode.
             
- In
            the scene view, click an edge of the polygon mesh where you want
            the edge loop selection to begin.
         
- Continue
            to click edges along the same contour line on the mesh, to create
            a partial loop selection of edges on the mesh.
            It’s not necessary that you click every edge
               along the path, just click once to specify the first edge and a
               second time along the same contour line along the mesh to indicate
               the end of the path.
             The Select Edge Loop Tool indicates
               the partial loop selection by selecting any edges that exist between
               subsequent edges you select.
             
- If
            you want to select a multidirectional edge loop path on
            the polygonal mesh, do the following:
            
               - In
                  the scene view, click on an edge of the polygon mesh where you want the
                  edge loop path selection to begin.
               
- Continue
                  to click on edges along the same contour line on the mesh to build
                  a partial loop of selected edges on the mesh.
               
 The Select Edge Loop Tool indicates
               the partial loop selection by selecting any edges that exist between
               the edges you’ve previously selected.
             
               - It’s
                  not necessary that you click on every edge along the path. Click
                  once to specify the first edge and a second time along the same
                  contour line along the mesh to indicate the end of the path.
               
- To
                  change the direction of the selection path, click the edge that
                  is directly adjacent to the edge you previously selected to indicate
                  the change in direction for the selection.
               
 
- When
            you have completed the desired edge loop selection, you can do one
            of the following to exit the tool:
            
               - Choose
                  the Select Tool in the Toolbox (Hotkey:
                  q).
               
- Choose
                  another tool or feature that performs the next operation on the edge
                  loop selection.
               
 For example, selecting the Move
                  Tool to move the selected edge loop, selecting 
                        Edit Mesh > Extrude to
               extrude the selected edge loop, or converting the edge loop selection
               to faces.
             
- If
            you want to cancel the edge selection, do one of the following:
            
               - To
                  cancel the selection of an edge,  + + on the
                  desired edge. on the
                  desired edge.
- To
                  cancel the selection of a portion of the edge loop,  + + on the
                  portion of the selected region. on the
                  portion of the selected region.
- To
                  cancel the edge selection entirely, click anywhere in the scene
                  view off of the mesh.
