Molecular modeling often involves precise manipulations of structures: positioning, aligning, and transforming intricate molecular geometries can be a tedious task. SAMSON, the integrative molecular design platform, offers a variety of intuitive Move Editors that simplify this process for modelers. These tools allow for translating, rotating, and aligning objects such as molecules, atoms, meshes, and more with precision.
What Are Move Editors?
Move Editors in SAMSON provide users with precise control over the position and orientation of molecular structures. These tools address common frustrations in molecular modeling, such as realigning molecules in the viewport or making rotational adjustments without losing accuracy. The available editors include the Displacer Move Editor, the Local Move Editor, and the Global Move Editor.
Displacer Move Editor
The Displacer is an easy-to-use editor that allows objects to be displaced in the plane of the screen (camera plane). Users can simply select nodes and drag them to reposition. This editor is particularly helpful for interactive simulations where quick adjustments are necessary. Shortcut: Press D to activate the Displacer Editor.

Local Move Editor
Perfect for working on specific molecular groups, the Local Move Editor is designed to translate and rotate selections along their principal axes. Additionally, users can manipulate structures using side translation widgets for axis-specific movements or leverage rotation widgets for precise angular adjustments. The Local Move Editor even features a trackball for freeform rotations.

Shortcut: Press M to activate the Local Move Editor. Highlights include:
- Central Translation Widget: Ideal for moving objects in the viewport’s camera plane.
- Axis Rotation Widgets: Intuitive curved arrows for rotating objects along specific axes.
- Dihedral Angle Adjustments: Quickly edit dihedral angles by clicking bonds to designate rotational pivots.

- Snapping: Enable rotational or translational snapping for consistent movements.

Global Move Editor
The Global Move Editor offers translation and rotation based on the global reference XYZ axes, making it a valuable tool for aligning structures on a project-wide scale. Similar to the Local Move Editor, it provides intuitive widgets for translation and rotation with snapping preferences for precision.

Shortcut: Press K to activate the Global Move Editor. This editor is especially useful for workflows where structures need to align with global axes or specific orientations in 3D space.
Make Your Modeling Workflow Smoother
The Move Editors are a cornerstone feature for anyone engaged in molecular modeling using SAMSON. Their precision, combined with intuitive controls, ensures that you can manipulate your models efficiently without frustration. Whether you need to fine-tune molecular alignments or make complex structure adjustments, these tools handle your needs seamlessly.
