Opening the Flowgraph Editor
To get started, we need to open up Sandbox. Sandbox contains the Flowgraph Editor as one of its many useful tools, and it can be opened via View | Open View Pane.
Note
You should always have a level loaded when opening the Flowgraph Editor, as flowgraphs are unique to levels. Flick back to Chapter 1, Introduction and Setup, if you've forgotten how to create a new level!
You've just accessed your first Sandbox tool! You should be presented with a new window with lots of subsections and features, but don't fret, let's tackle them one by one.
