When working on complex molecular structures, every action and adjustment you make builds on the last. But what happens when one of those actions doesn’t go according to plan? Or maybe you want to test a different idea without losing progress? This is where multi-level undo and redo capabilities in SAMSON become invaluable.
Why Undo and Redo Matter in Molecular Design
For molecular modelers, precision is key. Mistakes during structure editing, molecule building, or object transformations can be time-consuming to correct. A rich undo/redo functionality not only allows you to step back through errors but also enables iterative experimentation. Think of it as your personal molecular modeling safety net, letting you navigate through your work history effortlessly.
Tracking Document History in SAMSON
In SAMSON, each document maintains its own action history, meaning any modifications made are registered and can be reversed individually. This segmented approach ensures that you have full control over document-level changes without affecting others.
How to Access the History View
The History view in SAMSON provides a visual representation of past actions. Here’s how you can access it:
- From the menu: Go to Interface > History.
- Using shortcuts: Press
Ctrl + 3on Windows/Linux orCmd + 3on Mac.
The History view is your go-to tool for navigating previous states of your molecular structure with confidence.
Navigating Your Document History
Once the History view is open, exploring actions is straightforward. You can click on individual actions in the History panel to move to corresponding document states. Additionally, the Edit menu offers quick undo and redo commands:
- Undo: Use
Ctrl + Z(Windows/Linux) orCmd + Z(Mac). - Redo: Use
Ctrl + Y(Windows/Linux) orCmd + Y(Mac).
Understanding the Limits of Undo
It’s important to note that not all operations in molecular modeling are reversible. Actions that involve non-undoable processes might introduce constraints that prevent full reversions. For example, if you perform an irreversible change between two undoable operations, it may disrupt the undo sequence. To avoid unexpected loss of work, frequently saving different versions of your document can be a helpful safety measure.
Conclusion
Mastering undo and redo in SAMSON can greatly enhance your productivity and your ability to experiment with molecular structures. Whether navigating your action history or reversing a problematic change, these tools are indispensable for refining your models with precision.
