# Lattice from Volume Mesh

## About this Block

**What it does:** Creates a Lattice from a Volume Mesh with a configurable thickness and latticing method.

**Tips:**

* Choose from the following lattice creation methods:
  * **Mesh edges:** Creates lattice beams along the mesh edges.
  * **Vertex Centroid:** Creates a vertex at each mesh face's centroid and the mesh vertices. Lattice beams connect the vertices.
  * **Dual:** Creates a vertex at the centroid of each mesh face and creates connecting beams to the next closest mesh centroid.
* The Thickness of the lattice is a Scalar Field type, which allows for a variable Thickness.
* 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.
