A new DiaFlux model is created by inserting the following (empty) markup into the wiki article.

!! Handling Quality Problems
{{{

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.
{{{
%%DiaFlux
%
}}}
Drag and drop the questions of the questionnaire ''Quality Questions'' into the pane and connect the nodes as shown in the image depicted below.
[{Image src='DiaFlux Printer Quality.png' width='800' align='left' caption='The flowchart model for handling quality problems with the printer.' }]
\\

After saving the editor pane, the flowchart is saved as a new DiaFlux model as shown originally below.

!!! 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.
