Diagram View
When you focus on a single Blueprint inside the Blueprint Editor, the editor maximizes that Blueprint and fills the canvas with its diagram. This is the Diagram view — a flowchart of connected elements that represent your business logic.
- Double-clicking a Blueprint’s entry in the Contents sidebar
- Clicking the maximize icon in a Blueprint’s section header
- Clicking a Call node’s link to open the called Blueprint
Reading the diagram
Execution flows top to bottom. Each element is color-coded by type:| Color | Element type | Purpose |
|---|---|---|
| Green (circle icon) | Start node | The entry point where execution begins |
| Yellow | Decision | Conditional branching — evaluates a condition and routes the flow (IF / ELSE) |
| Yellow | Section header | Labeled group with a title and description that explains a part of the logic |
| Purple | Assignment | Performs a calculation or sets a variable value |
| Green (check icon) | Return | Ends execution successfully and returns output values |
| Red | Error | Ends execution with an error condition |
| Blue | Call | Calls another Blueprint as a sub-routine |
The right-edge toolbar

| Icon | Action |
|---|---|
| Sparkles | Open the AI prompt for the current selection |
| Book | Sync descriptions from logic — propose updated descriptions that match the current logic |
Code </> | Sync logic from descriptions — propose updated logic that matches the current descriptions |
| Undo / Redo | Step through your edit history |
| Settings | Canvas display options |
| Fit to view | Center and fit the diagram in the canvas |
| Plus / Minus | Zoom in and out |
Building and editing
Adding elements
You add new elements at connection points in the diagram — the small circles between existing elements. Click one to open the element palette, then select the element type you want to add. The palette offers: Assignment, Decision, Loop (items), Loop (counter), Loop (while), Error, Return, and Call. For a detailed guide on each element type, see Controlling the Flow.Editing elements
Double-click any element on the diagram to edit its configuration inline:- Decision nodes — edit the condition expression and branch labels
- Assignment nodes — edit the calculation or variable assignment
- Call nodes — select which Blueprint to call and configure input / output mapping
AI editing
Press Ctrl+I (or Cmd+I on Mac) — or click the sparkles icon in the right-edge toolbar — to open the AI prompt. The scope adapts to your selection: a single node, a section, or the whole Blueprint. See AI editing.Running and tracing
You can run the maximized Blueprint directly from the diagram. After a run, the execution path is highlighted on the canvas and the trace controls in the top toolbar become active — Step in, Step out, Previous, Next — so you can replay the execution step by step. While Live mode is on, the Blueprint re-runs automatically as you edit, and the Outputs footer at the bottom of the canvas updates continuously. For detailed instructions, see Test your Blueprint.What to do next
