Use lines to connect shapes and create diagrams or flowcharts

Flowcharts combine shapes and connector lines to show how steps relate. Here’s how to build a structured diagram in Canva using flowchart tools.

Canva includes a Flowchart shapes section in the

• Terminator: Start / End
• Process: Step or action
• Decision (diamond): Branching point
• Sub-process: Linked or repeatable workflow
• Data / Input / Output: Information entering or leaving the process.

Connector lines show how steps are linked in your flowchart.

To add a connector line:

• Press L on your keyboard.
• Choose a line from the
  Elements tab.
• Or go to Tools, then select Lines in the editor.

To connect a line to a shape:

1. Select the line you want to connect to a shape.
2. Drag the line’s endpoint to the edge of a shape.
3. When it snaps to the border, it’s connected.
4. Move the shape — the line will stay attached.

Double-click a connector to add a label, like Yes, No, or a condition. Labels make branches and transitions easier to understand.

As you build out your flowchart:

• Duplicate shapes to keep styling consistent (Shortcuts: Ctrl+D (Windows) or ⌘+D (Mac).
• Align shapes vertically or horizontally.
• Keep spacing consistent.
• Avoid diagonal lines unless necessary.
• Place decision shapes along the main path and label each branch clearly.
• Lines and shapes remain connected throughout layout changes.

Switch a shape type (e.g., rectangle to diamond) at any time. Connected lines stay attached and adjust automatically.

• Align and distribute shapes for a professional layout.
• Adjust layering so shapes appear above connectors.
• Group completed sections to protect structure.

The result is a clear, durable diagram suitable for team use or documentation.
