Split Grid

The Split Grid tool is used to split a grid domain into two sub-grid domains and may be selected with an RMC as shown in Split Grid#Figure 1.
Split Grid allows the user to create a polygon on an existing grid with LMC as shown in Split Grid#Figure 2. Closing the polygon with a RMC will generate a new grid inside the polygon as shown in Split Grid#Figure 3. The new grid layer will be created automatically on the Layer Control based on the existing grid layer.
