How to Customize Element Templates in Doc. Composer?

Getting Started

Download Article-Writing.vpp. You can also find this file at the bottom of this tutorial, under the Resources section.
Open the downloaded project file in Visual Paradigm.
Open the class diagram Domain diagram. The diagram is as below. In this tutorial, we are going to write a custom template that lists out the operations' details of all controller classes (i.e. classes with names ended with 'Controller').

Create an empty document

Select Tools > Doc. Composer from the application toolbar.
Click on Build Doc from Scratch.

Your screen should look like this:

Writing your template

We are going to produce a document that lists out the operations' details of all controller classes (i.e. classes with names ended with 'Controller') in a specific diagram. Here is the structure of document:

[class diagram image]
[for-each controller class]
[Class name]
[Table of operations]
[/for-each]

We are going to show you how to write an element template to produce such a document. To create a template:

Each element template has to be written for a specific kind of project data. It can be a diagram type, a model element type, or even a project. For example, if you want to write a template to list out all use cases in a use case diagram, you should write a template for use case diagram. To begin with, select the type of project data in Diagram Navigator or Model Explorer. In this case, select the class diagram Domain diagram in Diagram Navigator.
The Template pane lists the templates available for the selected element type, in this case, class diagram. If your Template pane is hidden, select View > Panes > Property from the application toolbar (or press Ctrl+Shift+P) to show it.
You have to duplicate an existing template in order to create your own. Right-click on ANY template and select Duplicate... from the popup menu.
In the Edit Template window, enter Controller Classes as the template name.

Copy the following template content and paste into the template editor.

Your template editor should look like this:
Entered template content

Click OK to save the changes.

Using your template

Now you've defined a template. Let's develop a document with it.

Select the class diagram Domain diagram from the Diagram Navigator.
Drag the template Controller Classes from the Template pane and drop it on the document.

You should see an image of class diagram, along with the details of controller classes presented in the document, like the following.
Click Export at the top-right corner of the document and select PDF Document from the pop-up menu.
In the Export PDF Doc. window, enter the output path.
Click Export. You obtain a PDF document like this:
