Update a Study Type

Make changes to a study type for Generative Design in Revit to refine its logic or regenerate its Dependencies folder.

1. Open the study type in Dynamo using one of the following methods:
   • Using Generative Design in Revit:
     • In the Create Study dialog, hover over the study type to update, and click Edit in Dynamo.
     • You may also open the study type this way while Dynamo is running. If you already have another graph open in Dynamo, you may see a message asking if you'd like to save changes to that graph.
   • Using Dynamo:
     1. In Revit, click Manage tabVisual Programming panelDynamo .
     2. In the Dynamo window, under Files, click Open.
     3. Navigate to the location where the study type resides, select its DYN file, and click Open.
2. Make desired changes to the graph and test them.

   See these resources:

   • About Creating a Dynamo Graph for Generative Design
   • Generative Design Primer
3. In the Dynamo menu bar, click Extensions Show Graph Properties and Show Graph Status.
4. If the Graph Status tab displays "Run graph to finalize validation," click Run in the bottom left corner of the window.

   This allows Dynamo to validate the graph before creating or updating the study type.

5. If the Graph Status tab lists any issues, resolve them before proceeding.

   For example, you may need to set nodes as inputs or outputs, or fix name conflicts. See Troubleshoot: Errors for Generative Design in Dynamo and Generative Design Primer: Setting up a Graph.

   Click the Issues tab of the tools pane for details. Click links in the issue descriptions to go to the relevant section of the graph. Make required changes, and re-run the graph.

6. When all issues are resolved, do the following in the Properties tab:
   • Description: Enter text to describe the purpose or use case for the study type. This information appears in the Create Study dialog.
   • Image: Add an image (PNG or JPEG) for the study type, such as a thumbnail from a sample outcome. Click in the field to navigate to the desired image, or drag and drop an image. On the Create Study dialog, the image is resized and cropped to a square to fit in the card for the study type.
     Note: Use PNG files or medium- to low-resolution JPEG files. High-resolution JPEG files can cause issues.
   • Author Name: Add the graph author's name.
   • Learn more URL: Add a documentation link. This can be accessed from the study type's icon in the Create Study dialog.
   • Custom Properties: Add custom properties by clicking the + icon. Rename the custom property by clicking the pencil icon. Custom properties do not appear in the Create Study dialog.
7. Save the graph. The study type is updated with the changes to its graph (DYN file) and any associated metadata.
