# Creating Multidiameter CMLs

> [!NOTE]
> Take note
> 
> This article explains how to create a CML with 2 Diameters, using CML Sections. The same methodology can be used for CMLs with more than two diameters..

To create a Multidiameter CML, you must configure its supporting settings and then create the CML itself. The process consists of seven steps:

- Configure the Settings:
  - 1. [Configure Sections for the applicable CML Type](/v414/docs/creating-multidiameter-cmls#configuring-sections-per-cml-type) so that each Section can have its own Diameter.
  - 2. [Assign Matrix Locations for your CML Type Sections](/v414/docs/creating-multidiameter-cmls#assigning-matrix-locations-per-cml-type-section).
  - 3. [Assign Measurement Points (MPs) for your CML Type](/v414/docs/creating-multidiameter-cmls#assigning-measurement-points-per-cml-type).
- 4. [Create an MP Configuration](/v414/docs/creating-multidiameter-cmls#creating-a-new-mp-configuration) that maps the assigned Measurement Points to Matrix Locations.
- 5. Create the Multidiameter CML:
  - 5. [Create the Multidiameter CML](/v414/docs/creating-multidiameter-cmls#creating-a-multidiameter-cml) by selecting the pre-configured CML Type.
  - 6. [Specify the different Diameters for each Section](/v414/docs/creating-multidiameter-cmls#editing-diameters-per-cml-section).
  - 7. Add the MPs from the MP Configuration to the CML ([Create Predefined Measurement Points](/v414/docs/creating-multidiameter-cmls#create-predefined-measurement-points)).

> [!NOTE]
> Take note
> 
> The same procedure applies when creating a CML with predefined Measurement Points that is not a Multidiameter CML. In such cases, you do not need to configure Sections. However, you must still configure Matrix Locations, Measurement Points, and an MP Configuration before creating the CML.

## Configuring Settings for a Multidiameter CML

In the Settings, you define how Multidiameter CMLs are structured and managed. This includes creating Sections for different Diameters, assigning Matrix Locations and Measurement Points to those Sections, and setting up an MP Configuration that links them together.

### Configuring Sections per CML Type

To add a Section to a CML Type:

- Navigate to [Settings \ Maintenance \ Configuration \ CML Types](/v414/docs/configuring-cml-types-in-settings).
- Select an existing CML Type (e.g., BENT PIPE) or click *Plus* to create a new one.
- Scroll to CML Section Configuration.
- Click *Plus* to add a new Section.

After selecting the applicable CML Type, click the Plus button to create a new Section.

- Enter a Name, Description, and assign a Color (e.g., red or #ff0000).
- Click **Save**.
- Repeat with additional Sections if needed. Each Section should have a unique color.

Two CML Sections with distinct colors are visible in the CML Section Configuration grid.

### Assigning Matrix Locations per CML Type Section

If no Matrix locations have been added to the CML Type:

- Scroll to the Set Matrixlocations grid.
- Click *Plus* to add a Matrix Location. Note: Matrix Locations are defined under [Settings \ Maintenance \ Configuration \ Matrix Location](/v414/docs/configuring-matrix-locations-in-settings).

A pop-up window will appear.

- Select the Matrix Location ID from the drop-down.
- In Section configuration, select the Section you want to link to the Matrix Location ID.
- Click **Save**.

- Click *Plus* in the Set Matrixlocations grid to add another Matrix Location to a Section.

If Matrix Locations were already added:

- Open the relevant Matrix Location by clicking the *Edit* button.
- Under Section Configuration, select the relevant Section.
- Click **Save**.

### Assigning Measurement Points per CML Type

- Scroll down to the Set Measurementpoints grid.
- Click *Plus* to add a Measurement Point (MP).

Click the Plus button to add a Measurement Point.

A pop-up window will appear..

- Select Measurement Point ID from the drop-down menu. Note: Measurement Points are defined under [Settings \ Maintenance \ Corrosion data \ Measurement Point](/v414/docs/corrosion-data-settings#measurement-point).
- Click **Save**.
- Repeat the steps until all relevant MPs for the CML Type are added.

Measurement points for CML Type added.

## Creating a New MP Configuration

To create a new MP Configuration:

- Navigate to [Settings \ Maintenance \ Configuration \ MP Configuration](/v414/docs/mp-configuration-settings).
- Click the *Plus* button.
- Populate the fields.
- In the Config field, enter a name for the configuration.
- Select the CML Type for which you want to add the new Configuration. Note: CML Types are defined under [Settings \ Maintenance \ Configuration \ CML Types](/v414/docs/configuring-cml-types-in-settings).
- Click **Save**.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_560.jpg?sv=2026-02-06&spr=https&st=2026-10-28T15%3A07%3A29Z&se=2026-10-28T16%3A07%3A29Z&sr=c&sp=r&sig=G2W7ASqdZ8M%2Bw7e0JnU4WqglKXQhtQ4BwrZSpibyR3k%3D)

Populate the fields and click Save to create a new MP Configuration.

- Select the newly created MP Configuration.
- In the grid on the right, select positions by clicking the relevant cells. Note: The X-axis shows Matrix Locations, and the Y-axis shows MPs.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_561.jpg?sv=2026-02-06&spr=https&st=2026-10-28T15%3A07%3A29Z&se=2026-10-28T16%3A07%3A29Z&sr=c&sp=r&sig=G2W7ASqdZ8M%2Bw7e0JnU4WqglKXQhtQ4BwrZSpibyR3k%3D)

Click on the cells in the grid on the right to select the positions.

Once the Settings are configured, you can proceed to create a Multidiameter CML.

## Creating and editing a Multidiameter CML

### Creating a Multidiameter CML

To create a multidiameter CML:

- Navigate to your [Circuit Details page](/v414/docs/pei-circuits-details-page#header).
- Scroll to the CML Section.
- Click *Plus* to [create a new CML](/v414/docs/creating-new-condition-measurement-locations-cmls).
- Fill in the required fields.
- Select the CML Type for which you created an MP Configuration in the steps above.
- Select the MP Configuration you created in the previous steps.
- Click **Save**.

### Editing Diameters per CML Section

Next, you need to define the Diameter(s) that differ from the rest by editing the CML:

- Click on the applicable CML on the Circuit Details page or on the CML Main screen to open it.
- In the CML Details section, click *Edit*.
- If not done yet, select the previously created MP Configuration.
- For each Section, either keep Inherit checked to keep the default Diameter, or uncheck Inherit and specify a new Diameter.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_565.jpg?sv=2026-02-06&spr=https&st=2026-10-28T15%3A07%3A29Z&se=2026-10-28T16%3A07%3A29Z&sr=c&sp=r&sig=G2W7ASqdZ8M%2Bw7e0JnU4WqglKXQhtQ4BwrZSpibyR3k%3D)

- Click **Save**.

### Create Predefined Measurement Points

Next, you need to add the MPs from the MP Configuration to CML, i.e., create the Predefined Measurement Points (PDMPs).

If the MP Configuration was assigned while creating the CML, MPs will automatically be migrated to PDMPs. Do not click Migrate, or duplicates will be created.

If the MP Configuration was assigned during editing of an existing CML, the Predefined Measurement Points in the Measurement Positions section will not be created automatically. To migrate the MPs to the PDMPs:

- Go to the Measurement Positions section.
- Click *Migrate* to convert MPs to PDMPs.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_566.jpg?sv=2026-02-06&spr=https&st=2026-10-28T15%3A07%3A29Z&se=2026-10-28T16%3A07%3A29Z&sr=c&sp=r&sig=G2W7ASqdZ8M%2Bw7e0JnU4WqglKXQhtQ4BwrZSpibyR3k%3D)

Click Migrate to Migrate MPs to Pre Defined MPs.

- Click *Save* in the Toolbar.
