   About 10 minutes

In this tutorial, we will use DataSeer to extract line numbers from a P&ID. We will then export the extracted data from DataSeer.

This tutorial is divided into the following sections:

• Learning Objectives - things you will know how to do after completing this tutorial.
• Setup - set up necessary before you get started.
• Instructions - instructions on how to complete the tutorial.
• Finishing Up - challenges and further reading for after the tutorial.

Learning Objectives¶

After completing this tutorial, you will know how to:

• Add projects and upload diagrams to them
• Extract line numbers from diagrams
• Export data from DataSeer for use in other documents

Setup¶

Before you start this tutorial, you must do the following:

• Contact your system administrator to get a DataSeer user account

Instructions¶

Now let's get started...

1. Obtain a P&ID¶

Store a P&ID containing pipes (line numbers) in PDF format to your local drive to be uploaded to DataSeer.

2. Add a Project¶

We now need to create a new project in DataSeer and upload your P&ID to it.

1. Access DataSeer.
2. Click NEW PROJECT.
3. In Project Name, enter "Line Number Tutorial".
4. Click the upload box and select your P&ID.

5. Click CREATE.

   DataSeer uploads your P&ID to a new project. Once the upload is complete, the new project displays under Your Projects.

6. Click LAUNCH.

   The project opens and your P&ID displays in the Diagram Viewer.

3. Extract the Line Numbers¶

The next step is to extract the line numbers from the P&ID.

1. Open the Text tab.

2. Click on the toolbar.

   The Search window displays.

3. Under Category Selection, select Line Number.

4. In Pattern, enter a regex pattern.

   Example

   The.+-.+-.+-.+-.+ pattern detects line numbers that contain four dashes -

   Tip

   Check out the Tips for guidance on how to use regex patterns to identify text.

5. Click SEARCH ALL PAGES.

   The Review window displays with the first matching line number. The line is also highlighted on the diagram for reference.

   

6. Review the matching line numbers:

   Info

   • To approve a match, ensure that the correct Id is extracted and adjust if necessary, then click APPROVE.
   • To approve all matches, click next to APPROVE, select Approve All, then click APPROVE ALL.
   • To reject a match, click REJECT.
   • To end the review at any time, click STOP REVIEW.

   Tip

   • Once you approve or reject a match, the next match displays for review. Continue until you review the full list of matches.
   • As you approve matching line numbers, they get added to the list on the sidebar.

7. Click on the toolbar.

8. Under Symbol Classes, select Line Numbers.
9. Review the approved matches on the print preview.

4. Export the Data¶

The next step is to export the line number data you extracted.

1. Click on the Navigation bar.

   

   The Project Library displays.

2. Click on the project and select Download Text data.

   DataSeer exports a CSV file into the Downloads folder for your browser.

3. Open the CSV file in a spreadsheet app, such as Microsoft Excel or Google Sheets.

   You can now add the data to your project documents.

   Example

   Here's an example of a line designation table featuring the line numbers we extracted in this tutorial:
