A selected subset of actions are presented as controls in the toolbar. The different sections in the toolbar can be dragged and positioned anywhere as small floating toolbars. Management of the toolbar is done by right-clicking on the toolbar and then manipulating the displayed menu.
#### 3D Views
In the main area of the application, several 3D views can be open at the same time. One of them will be active and the active view can be either maximized to use the whole main area, or normalized so that you can see all the open 3D views.
Most of the settings and features of ResInsight is accessible through the **Project Tree** and the **Property Editor**. Selecting an item in the **Project Tree** activates the corresponding 3D View, and shows the item properties in the **Property Editor** available for editing.
Toggling a checkbox next to an item in the **Project Tree** will toggle visibility in the 3D view. Toggling a checkbox for a collection of items will affect the visibility for all items in the collection. 
This Case type is based on a `*.GRDECL` file, or a part of an Eclipse *Input* file. This Case type supports loading single ASCII files defining Eclipse Cell Properties, and also to export modified property sets to ASCII files.
Each of the Eclipse properties is listed as separate entities in the **Project Tree**, and can be renamed and exported.
A **Grid Case Group** is a group of **Result Cases** with identical grids, but generally different active cells, initial values and results. These cases are called *Source Cases*.
The purpose of a Grid Case group is to make it easy to calculate statistics across the source cases both for static and dynamic Eclipse Properties.
ResInsight supports the following type of Eclipse input data:
-`*.GRID` and `*.EGRID` files along with their `*.INIT` and restart files `*.XNNN` and `*.UNRST`.
- Grid and Property data from `*.GRDECL` files.
#### Importing Eclipse cases
##### Eclipse Results
1. Select **File->Import->Import Eclipse Case** and select an `*.EGRID` or `*.GRID` Eclipse file for import.
2. The case is imported, and a view of the case is created
*TIP:* You can select several grid files in one go by multiple selection of files( Ctrl + left mouse button, Shift + left mouse button).
##### Eclipse ASCII input data
1. Select **File->Import->Import Input Eclipse Case** and select a `*.GRDECL` file.
2. The case is imported, and a view of the case is created
3. Right click the **Input Properties** in the generated **Input Case** and use the context menu to import additional Eclipse Property data files.
##### Handling missing or wrong MAPAXES
The X and Y grid data can be negated in order to make the Grid model appear correctly in ResInsight. This functionality is accessible in the **Property Editor** for all Case types as the toggle buttons **Flip X Axis** and **Flip Y Axis** as shown in the example below.

### Project files and Cache directory
ResInsight stores which cases you have imported and all the settings for each view etc. in a project file with the extension `.rsp`.
This file only contains references to the real data files, and even references to data files generated by ResInsight itself.
Statistics calculations, property sets you generate by using Octave, and well paths are saved to a folder in the same directory as you save the project file, and is named ProjectFileName_cache. So if you need to move your project, make sure you move this folder as well.
*TIP:* The `.rsp`-file is an XML file, and can be edited by any text editor.
Image export of current 3D view can be launched from **File -> Export -> Snapshot To File**. A snapshot can also be copied to clipboard using **Edit->Copy Snapshot To Clipboard**.
Eclipse Properties can be exported to Eclipse ASCII files by activating the context menu for a **Cell Result**.
