How to Use the Object Diagram Templates in Creately
- Choose a template that suits your needs
Pick a UML object diagram template. Click “Edit This Template” to open it and add object instances.
- Sign in or create a free Creately account
Create a free account or sign in. This lets you save your object diagram, return to it later, and keep every change synced to your workspace.
- Open the template and customize it
Show a snapshot of the system by placing specific object instances with their attribute values and the links between them.
- Add objects as instances (name : Class)
- Fill in concrete attribute values
- Draw links between related objects
- Represent a single moment/state of the system
- Keep it consistent with the class diagram
- Instance-level clarity
Model real example data as object instances to validate a class design against a concrete scenario—Creately keeps instances and links aligned.
- Collaborate with your team
Share for feedback. Give others view or edit access to your object diagram, gather comments inline, and resolve them without leaving the canvas.
- Save, export, or present
Finish and share. Save to your workspace, export the object diagram as PNG, JPEG, SVG or PDF, or present it live — then embed or link it wherever your team works.

Object diagrams complement class diagrams:
- Snapshots - the system at one point in time
- Example data - concrete instances with values
- Design validation - test a class model with real cases
- Debugging aids - visualize an object graph
- Teaching - show how classes become objects
A class diagram defines the blueprint (classes and relationships); an object diagram shows a real instance of that blueprint at a moment in time. Objects in the diagram should conform to the classes and associations you defined.
