After saving the article, KnowWE provides a link to visually edit the empty model.
When clicking the link, a new window with a visual editor is opened.
In the editor, you can drag an drop questions from the left menu pane into the editor panel.
Please insert a start node (from the toolbar) into the flowchart first.
Then we open the hierarchy ''Connection Questions'' from the entry ''Tutorial Printer Problems'' in the left menu.
We drag the questions from the left hierarchy into the editor pane and connect the nodes.
Please insert ''Connection Flow'' into the text field as the name of the flowchart.
After saving the editor the flowchart looks as depicted in the image below.

!!! Handling Quality Problems
As with the "Connection" segment of the knowledge base you also create a DiaFlux flowchart for printing quality problems by using an empty {{DiaFlux}} markup.

!!! Defining the Initial Questionnaire
After the definition of all subsequent problem areas, we define the entry of the knowledge base.
Here, the user is asked about the general problem with the printer and delegated to the already defined problem areas.
A new DiaFlux model is created by inserting the following (empty) markup into the wiki article.
{{{
%%DiaFlux
At line 270 added one line
}}}
At line 272 added 76 lines
As depicted in the image below, we also marked this DiaFlux model as the ''Autostart'' mode, i.e., the model started at the beginning of a user dialog.
[{Image src='DiaFlux Printer Entry.png' width='800' align='left' caption='Definition of the entry flowchart of the Printer Problems knowledge base.' }]
\\
\\
We see, that the question ''Please specify your problem'' is asked at the beginning.
Then, the DiaFlux flowcharts ''Connection Flow'' and ''Printing Quality Flow'' are called depending of the given answer.
%%DiaFlux
<flowchart fcid="flow_b77240b2" name="Printer Problem Entry" icon="sanduhr.gif" width="750" height="306" autostart="true" idCounter="20">

<guard markup="KnOffice">"Please specify your problem" = "Printer does not print"</guard>

</flowchart>

Now, the knowledge base is ready to use, since all terms are defined and connected by the DiaFlux models.
