Home lab and smart home diagrams

Over on the home lab, home networking and smart home subreddits, it has been fantastic to see diagrams of increasingly complex home computing and network setups being shared. Diagrams help home you understand the physical and logical connections between networked devices, and are useful for setting up security zones, upgrading hardware and debugging connection problems.

New networking shape library with customisable shadows

The new Network 2025 shape library in draw.io has extra styling options built in. When you enable the background colour, the shapes will have a bold long shadow. You can colour each part of these shapes individually - shape outline, shape fill colour (and neutral colour for internal details), background colour and gradient.

How to draw UML profile diagrams

Profile diagrams are one of the newer UML diagram types, providing a broad overview of a system showing how the system can be implemented in different domains. Stereotypes and constraints indicate which sub-systems and components, languages and processes are modified in different use cases.

Draw communication diagrams to simplify UML sequences

Communication diagrams (formerly collaboration diagrams) show the messages that are passed in a system as an action is taken or an event occurs, and in what order they are sent. As a simplified sequence diagram, these show the information sharing relationships more clearly between different elements of a system.

Timing diagrams for UML and embedded systems

Timing diagrams are important for activities that need to be completed within a specific time frame. Such as the ringing of a doorbell after pressing a button, or a ticket gate opening after a ticket has been validated.

UML interaction overview diagrams

Interaction overview diagrams show a high-level overview of how components of the system interact with each other. General flowchart shapes show the interaction flow between activities, and sometimes entire sequence diagrams or activity diagrams are embedded for detailed documentation.

What makes a good UML diagram tool?

There are a wide range of UML diagramming tools available, as standalone applications, as online-only cloud software, and embedded in various content platforms. Some take text input to generate diagrams, and others are specialised to draw just one type of UML diagram.

Create and share custom template libraries with draw.io

You can use custom shape libraries to store and share custom template diagrams, in addition to your favourite shapes, freehand sketches, and custom shapes. As you can also store icons, watermarks, images, parts of a diagram, and entire finished diagrams in custom shape libraries, they are an excellent way of sharing your custom templates with people outside your organisation.
An imported custom library will appear in the shapes panel on the left in draw.io

Use a waypoint shape to connect an association class in UML class diagrams

Association classes in UML class diagrams ‘hang’ off the relationship between two other classes. Instead of leaving an unconnected end on your connector, add a waypoint shape between them and connect all three class shapes to the waypoint shape.

UML component diagrams show the structure of a system

UML component diagrams are used to model the high-level software components and subsystems in service-oriented architectures and component-based development projects, and more importantly, define the interfaces between those components. As component diagrams provide a clear visual overview of a system, they are drawn early in a project as they are useful both to seek approval from stakeholders and to develop an implementation roadmap.

Draw UML activity diagrams

UML activity diagrams show the sequence of actions and the flow of control in a system or a process. You can model the behaviour of physical and digital systems, as well as business process flows with activity diagrams.

Draw a UML use case diagram

UML use case diagrams show all of the ways an end-user interacts with your systems, with all of its pre- and post-conditions, exceptions and alternate paths. These diagrams are used to establish your system requirements, whether that be a software system or an interaction with another person or team.

Create a sequence diagram

Sequence diagrams show the order of messages that are passed between elements of a system to complete a particular task or use case. The events that cross system boundaries are used by objects and people (actors) to complete their processes.

Create UML class diagrams

UML class diagrams are used to illustrate the structure of a computer program. They detail the types of data or attributes stored within each ‘class’, the methods (operations or functions) that each class provides, and the relationships between the classes.
