# How to create multiple lattice designs using lists

## Objective:

Learn how to create multiple lattice designs at the same time with lists.

## Procedure:

**1. Create a list of numbers.**

* Add a Sequence block. This block creates a list of numbers that increment by a constant amount.
  * Start: 0 mm
  * Increment: 12 mm
  * Count: 6

**2. Create an array of points.**

* Add a **Point List** block
  * Insert the **Sequence** block into the X input of the **Point List**. This creates a point at each spot specified in the sequence.

**3. Create volumes.**

* Add a **Box** block
  * Insert the **Point List** block into the Center Point input. This creates an object at each point.

![By inserting the Sequence list of 6 into the x input of a point block, 6 points are created in an evenly spaced line along the x direction. Then by inserting the point list into the center point input of a Box block, a Box is created at each of the 6 points.](https://files.learn.ntop.com/help-articles/lattices/1500003430262.png)

**4. Fill the boxes with a lattice.**

* Add a **Volume Lattice** block
  * Insert the **Box List** into the Volume input. By default, this fills each box with the same lattice. In order to fill each box with a different lattice, we need to use the **Volumetric Rule List** block and select six lattices.
  * Insert a **Volumetric Rule List** into the Unit type input. Choose 6 different lattices to iterate the box design

![Inserting the Box List into the Volume input of a Volume Lattice block, we can generate 6 lattices. The unit type input has a list of 6 different unit cells, which results in each lattice having a different unit cell configuration.](https://files.learn.ntop.com/help-articles/lattices/360104469073.png)

And that's it! You've successfully created multiple lattices on your design using lists.
