# Beams from Walls

Create beams selecting architectural walls

This command creates structural beams from walls, it creates all types automatically, it is possible to pre-establish the beam height, join these beams with nearest walls and utilize linked files along with other options.

{% hint style="info" %}
Onbox will automatically replace the existing Structural Framings, so you dont need to worry about duplicating elements.

**Position:**

* **Upper Beam:** Creates Beam on top of Selected Walls.
* **Lower Beam:** Creates Beam on bottom of Selected Walls. 
* **Inverted:** Creates an Inverted Beam on top of the Selected Walls. An inverted Beam is a Beam that its entire height is position on top of the Wall.

**Dimensions:**

* **Height:** 
  * **Fixed Height:** A fixed height specified by you.
  * **Span Divided by:** Onbox will calculated the beam height by the span divided by a number specified by you.
  * **To the Highest Opening:** The height of the beam will be the determined by the maximum opening found on the selected Wall.

{% hint style="info" %}
The Span is determined by the Length of the Beam minus the connected columns when applicable.
{% endhint %}

* **Width**:
  * **Wall Width Added to:** The Width of the Beam will be determined by the Width of the Wall plus a number specified by the user.
  * **Fixed Width:** The Width of the Beam will be specified by you.

**More Options:**

* **Join With Walls:** Onbox will try to automatically join the Beam with intersecting walls.
* **Links:** Allows Onbox to pick Walls on Links instead of the current Project.
