Create an Object Diagram Request a Demo

An object diagram is a type of UML diagram that represents a snapshot of system objects and their relationships at a specific point in time. It is essentially an instance of a class diagram and helps clarify classes, their attributes, and possible associations.

How to Create an UML Object Diagram with Your Team?

Open an Object Diagram Template

Start by launching Creately, and opening an object diagram template from the library, or launch a blank workspace to build from scratch. Use the Notes Panel or sticky notes to capture the scope and purpose of the object diagram so the team stays aligned.

Add Objects and Attributes

Customize the template to model your system objects. Drag and drop additional objects from the shapes library onto the canvas and define their attribute values (names, types, or states). Use sticky notes for extra details that provide more context.

Connect Relationships

Link objects with relationships such as associations, aggregations, or compositions. Use clear labels to define the type of relationship and show how instances interact at a specific point in time.

Customize for Clarity

Use the shape library, color themes, and icons to organize the layout. Apply formatting to highlight key objects and use @mentions or comments to clarify questions during collaboration with your team.

Review, Update & Share

Invite other stakeholders from QA, development, and security teams via email or link for real-time editing. Gather feedback with inline comments, refine the diagram, and share securely or export as PDF, PNG, SVG, or JPEG.

FAQs about Creately's Object Diagram Tool

What is the difference between an object diagram and a class diagram?

A class diagram shows the abstract structure of classes, attributes, and relationships. An object diagram, on the other hand, represents a snapshot of actual object instances and their links at a specific point in time.

Can I link my object diagram to other UML diagrams in Creately?

Yes. Creately allows you to connect your object diagram with related UML diagrams such as class diagrams, sequence diagrams, or use case diagrams, creating a unified workspace for your design.

Is Creately’s Object Diagram Tool cloud-based?

Yes. Creately’s object diagram creator is fully cloud-based, so you can access, edit, and share diagrams from anywhere, with changes synced in real time across devices.

How easy is it to create object diagrams using Creately’s Object Diagram Tool?

Creating object diagrams in Creately is very easy. With ready-made templates, an extensive shape library, and guided features, you can build accurate diagrams quickly without needing prior experience.

When should I use an object diagram in software design?

Use object diagrams when you need to model real-world examples of classes in action, analyze system states, validate class diagrams, or explain complex relationships to stakeholders in a concrete way.
