====== Use the 2D graph view ======

In this tutorial we will see how to visualize the project graph.

===== 2D Graph view=====
 
The 2D graph view can be opened by clicking on :

**Note:** The **2D graph** is different from the **2D View**. The latter cannot be used with 3d objects, which you usually have in your scene. Thus, it will most likely crash.

===== Visualizing different graph =====

A project in GroIMP contains a [[:01_user_documentation:06_graph:03_graphs:01_project_graph|project graph]]. The project graph is usually composed of several sub-graphs (the most commons are //Main Graph// and //Meta Graph//).

By default the 2D graph display the //Main Graph//:

The //Main Graph// is the graph usually managed by the users. It contains the Node 0, and usually the RGGRoot.

To select which sub-graph to visualize, use the menu "graph>edit":

It will open the attribute editor:

The currently displayed graph is called //project// (red circle in the image). __It is confusing but this is the //Main Graph//__. To change the selection click on //project// and select an other one. 

The other main sub-graph is the //Meta Graph// :
