Unit 00. Introduction to Blender, the NodeView and 3DView
*********************************************************

Sverchok Installed, what now?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you have a tickbox beside the Sverchok add-on in the Add-ons list in
User Preferences, then it’s safe to assume the add-on is enabled. To
show the basics you need to have a NodeView open, and it’s useful to
have a 3DView open at the same time.

NodeView and 3DView
-------------------

1. **Split a View**:

   To do this we can split the existing 3DView into two views, by
   leftclicking into the little triangle/diagonal lines in the bottom
   left of the 3dview, and dragging to the right.

2. **Switch a View**:

   Then you switch the resulting second 3DView to a NodeView (Node
   Editor)

3. **Sverchok Node Tree**:
   
   This icon |image2| shows that Sverchok Nodes can be loaded, you’ll see it among the other Node Tree types. |image3|


4. **Make a new Tree**:

   When you start out you will have to press the New button to make a new node tree called (by default) NodeTree

5. **Adding Nodes to the View**:

   From the NodeView, you can use the following ways to add nodes to tree:

   * Use the **Add** menu from menu bar:

     |image6|

   * Hit *Shift-A* (standard Blender's shortcut for adding things):

     |image7|

   * Hit *Ctrl-Space*. This shortcut calls for a special search menu, which allows you to search for nodes and macros:

   * Use Blender's standard search box, which appears when you hit *Space* in node view:

     |image9|

   * You can as well open the Tools panel by pressing *T* in node view. There
     is a special panel for each category of nodes. By pressing a button you
     add specific node to the tree:
