This guide explains how to prepare the service holes for CNC export before automating them using the **Detail Configurations** or **Smart Connections.** You'll need to set up the **Structural Framing** category **Service Hole** family **type settings.**

{% hint style="warning" %}
&#x20;Make sure to use the **Metal Framing** families (**Settings** > **Load Families** > **Detail Families**)
{% endhint %}

{% hint style="success" %}
Note: **Imperial** service hole families already include pre-set types for CNC machine brands.&#x20;
{% endhint %}

1. Navigate to the **Project Browser** > **Families** > **Structural Connections**
2. Find the **I\_SC Service Hole** (Imperial) or **M\_SC Service Hole** (Metric) family
3. Duplicate and rename any existing family type (not mandatory):

{% hint style="info" %}
When renaming a duplicated service hole family type, it's recommended to include your CNC brand name for clarity.
{% endhint %}

4. **Edit** the family **type**
5. Enter one of the values for the **CNC Type** parameter:

6\. Enter the service hole punch command in the **CNC Command** parameter.

{% hint style="warning" %}
Your CNC machine has specific punch command names for service holes (e.g. SERVICE\_HOLE, 3, etc.). The value in the parameter must match it.
