Creating Nodes (Instances)
BeginnerCreating Nodes (Instances)
Once you've defined Node Types in your metamodel, you can create instances (nodes).
Method 1: Drag from Toolbox (Most Common)
- Open a diagram on the canvas
- Find the Node Type in the Toolbox (left panel)
- Click and drag the type onto the canvas
- A new node is created and placed on the diagram
- The node gets a default label — click to edit it
- Fill in properties in the Properties Panel
Method 2: From the Tree View
- In the Tree View, find the Nodes section
- Click the + button
- Select which Node Type to create
- The node is created in the model (but not yet on any diagram)
- To add it to a diagram, drag it from the Tree View onto the canvas
Editing Node Properties
- Select the node (click on it on the canvas or in the Tree View)
- The Properties Panel shows all properties defined by its Node Type
- Fill in values — they save automatically
- You can also edit the node's label and description
Tips
- Nodes created via the Toolbox are automatically placed on the current diagram
- A node can appear on multiple diagrams
- Use meaningful labels — they're what you see on the canvas and in the Tree View
