Additional file can be attached to a model to elaborate it through its resource icon References. After that, you can open and view the inserted file through References. This page will show you how to add an external file to a model.
With VP-UML, you are able to show model elements in various diagrams to fit into different contexts. Two ways are provided to assist you in reusing model elements in different diagrams. This article will teach you firstly dragging and dropping from the tree to the diagram, secondly copying and pasting between diagrams and finally showing views.
Other tools often require users to go through a cumbersome process to create constructors. In contrast, Visual Paradigm enables users to create constructors effortlessly via a user-friendly pop-up menu.
