{% hint style="info" %}
**Note**: this guide applies to **Wall+M** Framing Configurations.
{% endhint %}

{% hint style="warning" %}
Make sure to use the correct **Structural Framing** families.

Metric:

* **M\_MF C+C\_CH Stud** - for vertical elements (studs, king studs, cripples, trimmers, etc.)
* **M\_MF C+C\_CH Plate** - for horizontal elements (plates, bridging/blocking, headers, sills, etc.)

Imperial:

* **I\_MF C+C\_CH Stud** - for vertical elements (studs, king studs, cripples, trimmers, etc)
* **I\_MF C+C\_CH Plate** - for horizontal elements (plates, bridging/blocking, headers, sills, etc.)

{% endhint %}

## 2. Choose the reversed cut type for Top and/or Bottom Plate <a href="#id-2.-switch-cuts-for-chosen-element-connections" id="id-2.-switch-cuts-for-chosen-element-connections"></a>

1. Go back to the **Framing Configurations** dialogue.&#x20;
2. Go to **Wall Framing**
3. Choose the tab **Top Plate** and/or **Bottom Plate**
4. Go to **Cut Type** and choose **Plate Cuts Stud**

## 3. Edit the plate family

### 3.1 Open the C+C\_CH Plate family

1. Go to the **project browser** > **Families** > **Structural Framing** category
2. Find the **M\_MF C+C\_CH Plate** (Metric) or **I\_MF C+C\_CH Plate** (Imperial).&#x20;
3. Right-click on the family and choose **Edit**:

### 3.2 Modify the Butt tf parameter formula

1. Go to the **Family Types** dialogue
2. Replace the existing **Butt tf** parameter formula with the new value:

```
1=2
```

3. Click **Apply**&#x20;

### 3.3 Create a new parameter

Create a new **Instance**, **Yes/No** parameter **Top\&Bottom** **Plate** and group it under **Model Properties**

<figure><img src="https://239424168-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqtUsszuAWXIZhQhrvjnb%2Fuploads%2FKdoSSzPa6trzCiFzIVL6%2Fimage.png?alt=media&#x26;token=d5be2d54-c55f-4dc7-9125-ce169257d19e" alt="" width="563"><figcaption></figcaption></figure>

### 3.4 Modify the existing formulas

1. In the **Lenghten\_Start** parameter, **replace** the existing formula by <mark style="color:red;">**copying**</mark> <mark style="color:red;">**the formula below**</mark>**:**

```
if(Cut Angle Start > 0°, Length Extension on Slope, Start Offset - if(or(Butt tf, and(not(Butt tf), not(Top&Bottom Plate))), Inverse Start Gap, End Gap))
```

2. Iin the  **Lenghten\_End** parameter, **replace** the existing formula by <mark style="color:red;">**copying**</mark> <mark style="color:red;">**the formula below**</mark>:

```
if(Cut Angle End > 0°, Length Extension on Slope, End Offset - if(or(Butt tf, and(not(Butt tf), not(Top&Bottom Plate))), Inverse End Gap, End Gap))
```

<figure><img src="https://239424168-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqtUsszuAWXIZhQhrvjnb%2Fuploads%2F4IiuAyLYhzn4Uu4ftAS2%2Fimage.png?alt=media&#x26;token=98bdc8ab-d27f-4b7c-9e67-9f877c0d9136" alt=""><figcaption><p>How the two formulas should look like</p></figcaption></figure>

3. Click **Apply**
4. Click **OK**

## 4. Load the family back into the project

1. Click **Load into the Project and Close**&#x20;
2. In the project, click **Overwrite the Existing Version**

## 5. Frame wall

1. Select the walls
2. Click **Frame Wall**

**Top/Bottom Plates** now extend to the end of the **Studs**:

{% hint style="success" %}
**Notch in the stud** **may not be visible** in Revit, but the **NOTCH** **command** **will appear in the CSV file**.
{% endhint %}

If the **Blocking/Nogging** also has a **reverse connection** with the stu&#x64;**, the plate** **will not extend** and **will not create the Notch** inside the stud:

{% hint style="warning" %}
**Note**: if you use <mark style="color:red;">**reversed connections**</mark> for the opening **Header** and **Sill** plates, the **Notches** will also appear in the **King Studs**.
