# Show periodic images

Makes copies of all particles to visualize multiple images of a periodic system.

## Parameters

Periodic images (X,Y,Z)

  Enables the generation of copies of the system in the three spatial directions. You can control how many times the system is duplicated in each direction.

Adjust simulation box size

  If this option is active, the simulation cell is also extended to match the size of the multiplied system.

## Usage note

When duplicating each particle, the modifier also copies all assigned properties including the particle's identifier. Thus, applying this modifier will lead to duplicate identifiers. Keep in mind that this may cause problems with other modifiers (e.g. the Manual selection modifier) that rely on the uniqueness of particle identifiers, and which following in the modification pipeline.
