## About this Block

**What it does:** The base block for creating all periodic lattices. It combines all of the building blocks to construct a lattice: the Unit Cell, the Cell Map, and the Unit Cell's parameters.

**Common uses:**

* Base block for all periodic lattices.

**Tips:**

* This block has three overloads: No Parameter, 1 Parameter, and 2 Parameters.
  * The overload and parameter names automatically update to match the Unit Cell's parameters
* Open up the block's Properties Panel to view the beam, implicit, and thick graph properties.
  * These properties are populated based on the type of Unit Cell you use. An error sign with a tooltip appears next to the property if it is empty.
