CSV (comma-separated values) file is a very common file format for saving textual data in table structure. Each line in the CSV file is presenting an entry, while fields in each record is speared by commas (or other separator). Data in CSV can be used with any spreadsheet program, or even for exchange of information between applications. In this article we will show you how you can make use of Visual Paradigm Open API to create a plugin which export the use case models in your project into a CSV file.
When creating diagrams sometimes you might want to have the shape showing different line styles, i.e. to have better presentation for your diagram with important elements easily spotted out. In this case you may adjust the line style to make the element looks different. To do this you can specify the line style of the individual element via the user interface. But instead of manually specify the line style shape by shape, you can also do this via the Open API. In this article we will use Class as sample to demonstrate how to control its line style with Visual Paradigm’s Open API. 
The generalization set defines a set of generalization relationship that describe how the superclass may be divided by a set of subclasses. The generalization defined in the set can group together in diagram for better presentation of the model. The generalization set can defined via the GUI on diagram or using Open API. In this article you will learn how to create generalization set using
