Using connector lines

📝 Note: This article reflects the classic BioRender canvas. For guidance on the updated experience, check out our article on the new canvas to explore key features and updates in the latest version.

Connector lines are a powerful tool in BioRender for creating diagrams, flowcharts, and logical pathways. By linking lines to icons, shapes, or text, you can build clear and structured illustrations that visually represent complex processes or relationships.

This guide walks you through how to insert, convert, and edit connector lines on your canvas.

Create a connector line

1. Click the Insert Line option from the top toolbar.

2. Choose your preferred line style.

• Note: Circular and bracket lines cannot be used to connect objects.

3. Hover over the object you want the line to start from.

• A connector icon will appear next to your cursor, indicating you can link the line.

4. Click and drag from the starting point and extend the line to another object.

• Note: You cannot connect a line to another line.

Convert a regular line into a connector line

1. Select an existing line on your canvas.
2. Drag the endpoints of the line to objects you want to connect.
3. Once connected, the line becomes a connector line and will stay linked to those objects.

Edit a connector line

You can edit connector lines just like regular lines using the toolbar.

Change the line type

1. Select the line.
2. Click on Line Type in the toolbar to choose a different shape.

Add and Move Nodes

1. Select the connector line.
2. Click on a white dot on the line to add a node.
3. Drag nodes around to adjust the line shape to your preference.

Adjust Placement

1. Drag the endpoints of the line to reposition it.
2. Fine-tune its placement using the Padding slider under the Tail and Head settings in the toolbar.

Troubleshooting

Can’t connect a line to an object?

• Make sure you're using a compatible line style (not circular or bracket).
• Check for the connector icon when hovering over the object.
