Interaction diagram software

Q: Can I build a UML diagram using markup?

Yes. First, you will need to enable the UML sequence diagram shape library. Then, Lucidchart provides a UML sequence markup feature that auto-generates a sequence diagram based on the text you provide.

Q: How can I change the formatting of a UML diagram?

You can add styling and formatting to your UML diagram using the Properties bar at the top of the Lucidchart editor.

Q: Can I show the difference between current and future states within the UML diagram?

Yes, use the layers feature to visualize current, ideal, or future states of any process or system side by side. Start with your current system and then create a layer depicting future states. Use hotspots to toggle between layers.

Q: What are the options for sharing my UML diagram in Lucidchart?

Publish and share diagrams with Lucidchart users and non-users via email, shared link, PDF, or image file. You can also share your diagram on social media or embed it onto any webpage.
