Multi-Cut Tool
If you want to split a face into more faces you can use the Multi-Cut Tool. With this tool extra vertices and edges are added. You can find this tool under:
Make sure the Multi-Cut Tool is selected in the Mesh Editing Tools section of the Modeling Toolkit window and use the Snap Step % setting to specify at what percentage increment to snap on an edge. Use Shift to enable snap mode.
The divisions shown in the settings are the number of divisions the new inserted edge will have. With the smoothing angle you can control how hard or soft the edges of your split geometry will be; use a low value (0) to let the edges appear hard. It can be really convenient to use snapping points along the edges. The number of points is the number of points per edge your mouse will snap to. These points are evenly divided along the edge. The snapping tolerance will determines how close the vertex needs to be to the snapping point before it snaps to it.
Now you can click and drag your mouse along an edge of the face you want to split. After that you can adjust the object further by going into component mode and moving the vertices or edges.
