The very first step that you need to follow is to install EdrawMax in your system. Instead of going through the complicated steps of understanding how to create a sequence diagram, you can check out EdrawMax steps, where we help you create a similar-looking sequence diagram in five steps. How to Create a Sequence Diagram in EdrawMaxĪs you saw from the above-mentioned steps, you can create a sequence diagram in Visio, but it will take an enormous amount of time and effort. Once you complete your sequence diagram, save it and keep it for future use.Ģ. You can also use Destruction to show the completion of the terms of a participant. The arrows on it represent the flow of information. You may use an activation bar that you can place on the lifeline to show the span of activity of a participant. There can be multiple types of fragments indicating the interactions between the lifelines. A self-message can indicate a recursive call, while an asynchronous message depicts an event that may not happen immediately. The Return Message shows a response to a previously-sent message. A message shape that can be used for transmission or requesting information. Now, drag it to the endpoint of the lifeline of the receiver. Click on the endpoint of the lifeline of the sender for that. You can use messages that you should send between the lifelines. The yellow control point allows you to increase or decrease the timeline. Double-click on the lifeline to enter the title. ![]() You can click take actor lifelines for the participants and object lifelines for elements. Now take shapes from the Shapes window from the diagram and rename them by double-clicking the labels. To make the connection points visible when connecting the shapes, tick the checkbox next to Connection Points. After selecting the black template, set Metric or US units for the project.Ĭlick on ' Create.' Now, take shapes from the Shapes window present at the Task Panes of View option. Launch the Visio on your system, and then take the UML Sequence diagram to begin your sequence diagram. You can also plan your sequence diagram before starting your work. While making a sequence diagram, it is better to have an apt idea of how the tool functions and how to make a sequence diagram. How to Create a Sequence Diagram in Visioįollow these simple steps to create a sequence diagram in Visio. Also check out this comprehensive Sequence Diagram Tutorial to learn more about sequence diagrams.1. As always, we do encourage you to get in touch with us with any feedback or queries that you may have. What we have covered here are the basics of the sequence diagram, which should allow you to model most of the interactions that will take place in a common system. Inside the frame’s content area the loop’s guard is placed towards the top left corner, on top of a lifeline. You draw a frame, and in the frame’s namebox the text “loop” is placed. The loop combination fragment is very similar in appearance to the option combination fragment. In UML 2, modeling a repeating sequence has been improved with the addition of the loop combination fragment. This is something that is used when you need to model a repetitive sequence. Loops are rather basic and easy to grasp. If the student’s past due balance does not equal zero, then the sequence skips sending any of the messages in the option combination fragment. We include a guard for the option however, the guard is not a required element. According to the diagram, if a student’s past due balance equals zero, then the addStudent, getCostOfClass, and chargeForClass messages are sent. The image below uses an option combination fragment since a lot of messages have to be sent if the student’s past due balance is equal to zero. ![]() ![]() An option is usually used to model a simplistic “if then” statement, for example, if there are less than five donuts present on the counter, then make two dozen more. ![]() The option combination element or fragment is utilized to model a sequence that will occur provided it is given a certain condition. The word “alt” is placed inside the frame’s name box. As you can see below, will notice that an alternative combination fragment element is drawn using a frame. Alternatives allow the modeling of the “if then else” logic (e.g., if you were to buy three items, then you get 20% off your purchase whereas you get 10% off your purchase). This type of elements is utilized to indicate a mutually exclusive choice that exists between more that one message sequence. These would consist of Alternatives, Options and Loops. In this concluding post, we will take a look at the elements known as Combined Fragments. Lifelines, Messages and Guards) that were related to Sequence Diagrams. As we mentioned in the last post – The Basics and Purpose of Sequence Diagrams ~ Part 1, we did discuss three of the main elements (i.e.
