# Periodic Lattice
In the *Lattices* tab, we have the **Periodic Lattice** block, which creates all of the periodic lattices in nTop. The block generates these lattices through**Unit Cells**and **Cell Maps**. Using this block, we can create a lattice with a custom implicit design, a TPMS structure, or a graph.
The**Periodic Lattice** block has three key inputs: *Unit Cell*, *Cell* *Map*, and *Unit Cell Parameters*. In the next few lessons, we will go into detail about these inputs and how to create a lattice using this block.
