## Steps

### Step 1: Navigate to Pile

Navigate to **Substructure > Pile** in the tree view.

### Step 2: Assign Foundations

Click the **three-dot icon** on the **Substructure** cell and select the footings.

The number of piles placed under each foundation according to the project specifications:

| Foundation | Number of Piles |
| ---------- | --------------- |
| RF1        | 9 piles         |
| RF2        | 9 piles         |
| F1         | 25 piles        |

### Step 3: Define Pile Section Data

Click the **three-dot icon** on the **Section Data** cell and select **Edit**.

Enter the following parameters for **P1** (Pile):

| Parameter                              | Value   |
| -------------------------------------- | ------- |
| Section Length (Starts from Top) \[ft] | 25      |
| Start Section                          | PileSec |
| End Section                            | PileSec |

### Step 4: Apply Section Data to All Piles

Apply the section data from the previous step to **all piles** in the project, as they are identical.

### Step 5: Define Pile Offsets

Enter the **Longitudinal Offset** and **Transverse Offset** from the footing origin for each pile.

### Step 6: Configure Pile Properties

Navigate to the **FEA** tab.

Click the **three-dot icon** on the **Pile Properties** cell and select **Edit**.

Edit the **Tx/Ty/Tz/Rz** properties in the Pile Properties spreadsheet as shown in the figure.

### Step 7: Apply Properties to All Piles

Apply the Pile Properties data from the previous step to all piles in the project, as they are identical.

### Step 8: Enter Pile Capacity

Enter a **Pile Capacity** of **360 kip** for each pile.

<summary><strong>Quick Tip:</strong> Transverse Offset Direction</summary>

Offset values use PGL (Project Geometry Line) as the reference point.
