## About this Block

**What it does:** Creates directional ribs from the beam elements of a Lattice.

**Tips:**

* The Direction input requires a field to derive the normal direction from.
* Each beam's Height is measured from the surface of the initial lattice.
* The Direction, Height, and Thickness inputs are all scalar field inputs that can use the **Ramp** block to vary the properties of the ribs.
* The outward direction of the implicit body used in the Direction input is the positive direction of the field.
* 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.
