# Contextualize engineering diagramsDeprecated


We are deprecating this feature from August 1st in favor of Create interactive engineering diagrams.

Extract information from static engineering diagrams, typically P&IDs (Piping and Instrumentation Diagrams), to create fully contextualized and interactive diagrams that you can navigate on any device.

Use CDF to find, extract, and match tags (the identifiers for equipment and file names), and automatically link them to an asset hierarchy and any associated resources, such as time series, files and sequences. Then let domain experts validate and fine-tune the results.

The engineering diagrams must be single-page PDF files containing a diagram with tags or an image of a diagram with tags.

# Step 1: Select engineering diagrams and assets to match


  1. Navigate to fusion.cognite.com (opens new window).
  2. Sign in with your CDF project name and credentials.
  3. Select Create interactive engineering diagrams in the menu.
  4. On the Contextualization pages, select the engineering diagrams you want to make interactive and then the assets you want to match the engineering diagrams to.
  5. Optional: Use the Data set, Search and Source system to filter the diagrams. For assets, you can also filter by root asset.

# Step 2: Select engineering diagrams options

Use the Select options page to configure the matching of diagrams to assets.

  1. Optional: Select Allow partial matches to include matches where the diagrams tag names do not exactly match the asset list. CDF finds matches by comparing similar characters, such as 0 and O, 8 and B. Clear this option to only allow exact matches.

  2. Optional: Select Grayscale diagrams to increase the speed of the matching and create SVG files with smaller file size. Clear this option to generate SVG files with the original source colors.

  3. Select Next to start matching engineering diagrams and CDF resources.

# Step 3: Validate interactive engineering diagrams and update CDF

For each engineering diagram CDF shows the tag types it has detected:

  • Files: Tags to other engineering diagrams
  • Assets: Tags to other assets in CDF
  • Unclassified: Tags that are already manually linked to other resources
  1. To validate the automatic results, select View to display the interactive engineering diagrams.

  2. In the interactive view, you can inspect and validate the automatic results, and you can manually add new tags or search for similar tags and link them to assets or files.

    • To add new tags:

      Add tag link

      1. Select Actions and Add new tags.
      2. Draw a bounding box with the mouse pointer around the tag you want to add.
      3. Choose the asset or file you want to link to.
      4. Select Add tag link.
      5. Select Finish adding.
    • To search for similar tags:

      1. Click Action and Find similar objects.
      2. Draw a bounding box with the mouse pointer around the object you want to search for similarities for.
      3. Click Find similar tags.
      4. Choose the asset or file you want to link to.
      5. Click Add tag link.


  3. You can update CDF with individual diagrams from the interactive view, or you can bulk update diagrams from the results page.
