## About this Block

**What it does:** Extends open beams within a Lattice by using a Body input to select which beams to extend.

**Tips:**

* The Region input allows for following selection methods:
  * **Inside:** Selects open beams inside the Body.
  * **Outside:** Selects open beams outside the Body.
  * **Boundary:** Selects open beams on the surface of the Body.
* Adjusting the Tolerance input value determines which beams are considered inside, outside, or on the surface.
* 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.
