Welcome to our quick guide on using connector lines in BioRender! Connector lines are a handy tool for effortlessly creating pathways, flowcharts, and diagrams by linking lines to icons, shapes, or text on your canvas.

Creating Connector Lines

  1. Click the Insert Line option in the toolbar
  2. Select the line style you want. Note: circular and bracket lines cannot be used to connect objects.
  3. Hover over the object you want to start the line from. A line will be connected to an object when you see this icon show up beside your cursor.



  4. Click and drag from the point you want to start the line from. Drag the end of the line to another object. Note: you cannot connect to another line.

You can turn an existing line into a connector line by dragging the end points of the line to objects you want to connect to!

Editing Connected Lines

You can adjust the look of a connector line in the toolbar just like any other line.

Change the shape of the connector line by selecting the line you want to edit and choosing a different shape under the “Line Type” option in the toolbar.

You can customize the shape of a connector line by moving around the nodes on the line. Select a connector line and click on a white dot on the line to add new nodes. Drag the nodes around to change the shape of the line.

You can edit the placement of your connector lines by dragging the endpoints to your desired location and fine tune the placement by using the “Padding” slider under the Tail and Head options in the toolbar.
