3D Views are the windows displaying the Grid Models. The visualization is controlled by the **Project Tree** item representing the **View** and their subitems. Each item has a set of proerties that can be editied in the **Property View**.
The **Cell Result** item defines which Eclipse property the View uses for the main cell color. The property can be chosen in the property panel of the **Cell Result**. The mapping between cell values and color is defined by the **Legend Definition**  along with some appearance settings on the Legend itself. (Number format etc.)
When working with a reservoir model, it is useful to map a set of grid cell properties in the same view. This can be achieved by activating **Cell Edge Result**. When selecting a result variable for cell edge, a second legend shows up in the 3D view in addition to different color mapping along the edges of a cell. Color legend management is available when selecting **Legend Definition**.
Using range filters enables the user to define a set of IJK visible regions in the 3D view. A single IJK-slice can be added from the context menu when rightclicking a grid cell. A new range filter can also be added by activating the context menu for the **Range Filters** collection in the **Project Tree**.
In addition to range filters, it is possible to filter visible grid cells based on a property value range. Add a new property filter by activating the context menu for **Property Filters**. The new property filter is based on currently selected cell result.
Select **Wells** in the **Project Tree**. In the **Property Editor**, select **On** for **Add cells to range filter**. This will hide cells not part of a well.
In addition, all cells along a direction can be added as a fence. Enable this by checking **Use well fence**.
