{{< image-center

    alt="The Modular SimObject Node Graph" >}}

This window will open automatically when you open or create a **modular SimObject**. The window will show the hierarchy of nodes and how they will be compiled together when one of the SimObject *presets* is loaded into the simulation. If this window is not visible, you can open it from the [View](../menus/#h1) menu of the SimObject Editor.

Within this window you can *left-click* on any node then drag it around to re-position it, or you can *left-click{{< mouse-press >}}* in the window and *drag* to select multiple nodes at once. You may *left-click{{< mouse-press >}}* on any of them and *drag* to move them all together. If you *right-click{{< mouse-press "right" >}}* on an empty part of the graph, you will be shown the following menu where you can choose to create a new node:

    alt="The RMB Menu To Create A New Node" >}}

If you *right-click{{< mouse-press "right" >}}* on a **node** then the menu will change to show the following:

{{< image-center
    src="images/2_DevMode/simobject_editor/simobj_main_11_graph_rmb.png"
    alt="The RMB Menu When Right Clicking On A Node" >}}

Here you will be shown the **name** of the node you clicked on, and then have the following options:

-   **Open In Explorer** - Open the file explorer on the location of the node that was clicked-on.
-   **Rename** - Rename the node.
-   **Delete** - Delete the node.



You can also *right-click{{< mouse-press "right" >}}* on any **edges** to open a small menu where you have the option to **delete** the edge.

After adding a node to the aircraft, it will automatically be connected with the **common** node, and then you can click on the blue-bar and then drag to create an **edge** between the new node and one of the existing nodes.

    alt="Example of Creating An Edge Between Two Nodes" >}}

To help with the visual layout, edges can also be *split* so that they can be arranged to "fit" the available nodes. This may be done automatically if you use the Reset menu option, or you can do it yourself by clicking and *holding* the left mouse button{{< mouse-press >}} on an edge and simply dragging. This will create a control point which can then be moved around to reposition the path of the edge between two nodes:

    alt="An Edge Control Points" >}}

If you need to remove a control point then simply *double-click{{< mouse-press >}}* on it and it will be deleted.


### Menu

There are a number of menus available at the top of the graph view window. These are explained below.


#### Create

{{< image-center
    src="images/2_DevMode/simobject_editor/simobj_graph_1_menu.png"
    alt="The Create Menu" >}}

From this menu you can create new **Preset**, **SimAttachment**, or **Livery** nodes.


#### View

{{< image-center
    src="images/2_DevMode/simobject_editor/simobj_graph_2_menu.png"
    alt="The View Menu" >}}

From this menu you can choose the **Show Only Selection** option, which will "isolate" nodes that you *left-click{{< mouse-press >}}* on. When a node is clicked with this option, you will see only that node and its direct connections in the hierarchy:

    src="images/2_DevMode/simobject_editor/simobj_main_12_graph_selection.png"
    alt="Example Of Node Isolation Using Show Only Selection" >}}

Additionally, this menu has the option to **Show Thumbnail**s. WHen this is active, nodes will also show the thumbnail image associated with them (when appropriate):

{{< image-center
    src="images/2_DevMode/simobject_editor/simobj_main_13_graph_thumb.png"
    alt="Thumbnails Showing In The Graph View" >}}


#### Layout

{{< image-center
    src="images/2_DevMode/simobject_editor/simobj_graph_3_menu.png"
    alt="The Layout Menu" >}}

From this window you can **Save** the current window layout so that it will be loaded the next time the editor is opened. You also have an option to **reset** the layout, which will reset all node and edge positions to their default positions.
