# Well Seeker X: Adding an IPM
## Introduction
Well Seeker X comes pre-installed with the latest generic surveying error model tool codes issued by the ISCWSA. However, on occasion the user may want to add their own custom tool codes to the software. Usually this is to model the survey performance of a specific tool.
Most surveying tool manufacturers issue their tool codes as IPM (Instrument Performance Model) files with the “**\*.IPM**” file format. If the user has received an IPM file they can follow the instructions in **Method 1** below to add it to Well Seeker X. If the user does not have the IPM file but has the details of the tool code, they can enter them manually into Well Seeker X by following the instructions in **Method 2**.
### Method 1 - If the user has an IPM file
1. Open Well Seeker X. Select the **Settings** tab and select **Open** in the Setup File section. This will open the Well Seeker Roaming folder in a new window.
2. Open the **IPM** folder.
3. Close Well Seeker X.
4. Paste your IPM file into the IPM folder.
5. Open Well Seeker X.
6. Your new IPM will now be available to select from the dropdown menus in the **Survey Properties** window and the **Plan Properties** window.
### Method 2 - If the user does not have an IPM file
1. Open Well Seeker. Select the **Tools** tab and select **Survey Tools** from the **IPM Files** section.
2. Click the **Add new IPM** button.
3. Enter a suitable file name and hit save.
4. Search for the new name in the Search field, select the relevant option in the Survey Tools table and then click on the **Edit** button.
5. If required, you can enter a new name for the survey tool in the **Survey Tool Name** box, and a description in the **Description** box. Enter the relevant co-efficients into the table. As you enter a row into the table, the software will create a fresh row underneath so that you can continue. When you are finished, click on the **Save** button.
6. Your new IPM will be available to select from the dropdown menus in the **Survey Properties** window and the **Plan Properties** window.
