In molecular modeling, clarity is paramount. Labels play a key role in annotating specific nodes, molecules, or measurements within a molecular system. However, managing the visibility of these labels effectively can significantly enhance clarity and reduce clutter in your designs. If you’re working with SAMSON, understanding how to control the visibility of labels in the viewport is crucial. Here’s a comprehensive guide to help you fine-tune your labeling setup and ensure your molecular models stay insightful and organized.
Optimizing Label Visibility
Labels in SAMSON automatically adjust their visibility based on the zoom level in the viewport. This dynamic behavior ensures that labels for smaller nodes (like atoms) fade out when zooming out, while labels for larger nodes (like molecules) remain visible and vice versa when you zoom in. This is an excellent way to maintain a clear overview of your model without manual adjustments.
Here’s how to control and customize label visibility:
Show or Hide Labels
To toggle the visibility of labels, simply open the Document view in SAMSON and tick or untick the labels. This allows you to quickly declutter the scene when needed.

Zoom-Dependent Visibility
Labels are designed to change their visibility progressively as you zoom in and out of your molecular system. For instance, zooming out hides labels for smaller nodes like atoms, while highlighting larger nodes like molecules. Such automatic scaling can be particularly useful when working with complex structures.

Customizing Display Radii
To further refine when labels appear or disappear, you can adjust their maximum and minimum display radii. Simply select a label and go to the Inspector. There, you’ll find options to set these radii, allowing you to determine the display thresholds for each label.

Enhancing Workflow Efficiency
By mastering these features, you can ensure that only the most relevant labels are visible at any given moment. This reduces cognitive overload and allows you to focus on the essential elements of your model. Whether you’re preparing your molecular design for presentation or deep analysis, controlling label visibility ensures a clean and professional result.
