Labels play a crucial role in molecular modeling, offering a clear way to annotate and highlight important structural features. However, positioning these labels accurately in relation to the viewport can be tricky, especially when working with complex systems. If you’ve struggled with arranging labels just right while maintaining clarity in presentations or analysis, here’s a solution to your problem.
Why Moving Labels Matters
When labels are created in SAMSON, they are placed at the geometric center of nodes in the viewport plane by default. This positioning often needs fine-tuning to avoid overlap with other elements, enhance readability, or align annotations for a polished presentation. The good news? SAMSON provides versatile tools to move labels easily and customize their placement as needed.
How to Move Labels in SAMSON
Here are three effective techniques for moving labels to their ideal positions:
- Adjust the viewport offset: Select a label and use the Inspector to change its viewport offset. This lets you control the label’s position relative to its associated nodes quickly.

- Use move editors in the viewport: Set the Selection filter to “Labels” and activate a move editor, such as the Displace editor. You can access it through the icon (
) or by pressing the D key. This intuitive method lets you drag and reposition labels directly in the Viewport for precise placement. 
- Use the document view: You can also select a label in the Document view, then apply move editors to reposition it. Like the second method, this provides excellent control over label placement.

Take Control of Your Molecular Models
Each of these methods offers flexibility and precision, enabling you to manage intricate details in your molecular models. Keep in mind that moving labels is just one aspect of refining your annotations; SAMSON also allows customization of label colors, fonts, and visibility thresholds to elevate your molecular design work.
