BioRender has two primary features to help you align shapes, icons and text with one another in your image: the alignment tool and the grid.
The Alignment Tool
The alignment tool can be used to accurately align objects according to the edge or center of their selection box.
To remove the banner:
1) Select the collection of objects to wish to align (click and drag across objects to select them, or hold Shift and click on each object to add it to the selection).
2) Click on the Align button to expand the Align Menu, then select an axis to align the objects along (right, left, center, etc).
Applying a Grid
Gridlines can help you align objects in your illustration. When you apply gridlines, you can easily snap components to the gridlines.
1) Click Show Grid (under the zoom slider) and click the "+" and "-" buttons to increase or decrease the size of the grid to your liking.
