This extension makes it possible to rapidly create advanced patterns from selections:

1. Select the structures you want to replicate. This can be any number of atoms and bonds.
2. Use the widgets to translate and rotate the copies. You can press the Control / Command key and click on a widget to enter a precise value for a translation or rotation. You can also use snap displacements to chosen lengths and angles.
3. Control the number of copies by clicking on the main UI widget. You can use the mouse wheel to increase and decrease this number. You can also press the Control / Command key while using the wheel to increase and decrease the number of copies faster.
4. Press accept to complete the model.

In the main preferences (Edit > Create array), you can choose:

• whether copies are automatically merged when they are nearby.
• whether hydrogen atoms are automatically adjusted.
• whether copies create new structures or are combined with existing ones.
