# Create interactive diagrams
> Extract information from static engineering diagrams to create interactive diagrams that you can explore on any device.
Use this contextualization tool to find, extract, and match tags on engineering diagrams and link them to an asset hierarchy or other resource types, such as files. You can approve or reject the results at any time.
An engineering diagram with new tags has the status **Pending approval**. This status means that there are detected tags that need to be either approved or rejected to ensure that the interactive diagrams are accurate.
For each engineering diagram, CDF shows the tag types it has detected:
* Tag type **Diagrams**: Tags to other engineering diagrams.
* Tag type **Assets**: Tags to other assets in CDF.
* Tag type **Unlinked**: Tags that are already manually linked to other resources.
## Create interactive diagrams
Navigate to **Data fusion** > **Contextualize** > **Diagram parsing**.
Select **Create interactive diagrams**.
Select the diagrams that you want to make interactive.
You can filter the diagrams by **Name**, **Data set**, **Label**, or **File type**, such as PDF. For assets, you can also filter by **Root asset**.
The supported interactive diagram file mime\_types are application/pdf, image/jpeg, image/png, and image/tiff. For more information, see [API documentation for engineering diagrams](/api-reference/concepts/20230101/engineering-diagrams).
Select **Next step** to continue.
Select the diagrams you want to link your diagrams to and select **Next step**.
Select the assets you want to link your diagrams to and select **Next step**. This limits the matching to assets from the same plant or unit as the selected diagrams.
Select a contextualization model:
* The **Standard model** is selected by default as this model is recommended for most engineering diagrams.
* The **Advanced model** lets you configure options such as the number of tokens matched for an entity, partial matches, and field matching.
Select **Next step**.
Activate **Save and skip settings** if you always use the same model.
Select **Run model**.
Review the result of the model - newly detected tags on the interactive diagrams.
Select **Approve all**, **Preview all**, or select a diagram to review it individually.
### Approve or reject detected tags
Select the bounding box around the detected tag in the diagram.
Select **Approve tag** or **Reject tag**.
Select **Save**.
You can also approve or reject tags like this:
Select a diagram to review it individually.
If the diagram has tags, select **Asset** or **Diagram** on the right sidebar to review them.
Select the pending tag - outlined in blue.
Select the tag you want to review.
Select **Approve tag** or **Reject tag**.
Select **Save**.
### Add new tags
Select the pencil icon to open edit mode.
Use the mouse pointer to draw a bounding box around the tag you want to add.
Select **Add manually** and select the CDF resource in the list you want to link to.
Select **Save**.
## Review engineering diagrams pending approval
You can filter the diagrams that are pending approval by **Name**, **Data set**, or **File type**.
Select the **More options** icon on the diagram.
Select **Recontextualize diagram**, **Approve pending tags**, **Reject pending tags**, or **Clear all tags** on the diagram. If you select **Recontextualize diagram**, you restart the process.
## Save diagrams as SVG
Select **More options** icon or select **Save as SVG** button.
You can save the files as SVG with the same names or specify a prefix.
Select **Save files**.
For information about the new diagram parsing, an upgrade from asset-centric to a data-model approach, see [Diagram parsing for data modeling](/cdf/integration/guides/contextualization/diagram_parsing).
