Known issues for Generative Design in Revit
Create Revit Elements fails to complete when Dynamo is pre-launched
Symptom: You open a study type in Dynamo, select inputs for the study, and click Generate. Once the study has completed, you select an outcome and click the Create Revit Elements button, but nothing happens.
Issue: This issue occurs when a study type's graph is open in Dynamo while you create a study. A save confirmation dialog within Dynamo is preventing the element placement from completing.
Work-around: Switch to Dynamo and dismiss the save dialog, and the element placement should complete. Alternatively, make sure Dynamo is not open when you start creating your study.
Manage Folders is not sensitive to dynamic folder changes
Symptom: You use Manage Folders to add a folder, close the Manage Folders dialog, and then delete the folder on disk. On the Create Study dialog, for Choose Folder, if you select that folder, Generative Design correctly displays a warning for the missing folder. However, if you then undo the folder deletion on disk and reopen Manage folders, the folder is still displayed with a warning.
Issue: This issue occurs because the folder state is now out of date in Manage Folders. This issue may apply to any changes to files or folders during the Generative Design session.
Work-around: In the Manage Folders dialog, delete any out-of-date folder entries, and add them again.
When exporting design outcomes, camera views for geometry are not stored
Symptom: If you edit the camera view for the geometry in a design outcome, the new view of the object will not be stored on disk, and the change will not be reflected in the image files created when exporting data for that study.
Work-around: If you would like to generate new static images for your designs, set the camera angle in the underlying Dynamo graph and re-run the study.
Previously created studies don't support infinite scroll or image export
Symptom: Studies generated before the 22.3.10 update will not support infinite scroll or image export.
Work-around: To export images for a study created before the update, re-run the study.
The study type runs normally, but the Graph Dependencies dialog shows missing dependencies
Symptom: You open the Graph Dependencies dialog for a study type. The dialog shows missing dependencies. However, the study type runs normally.
Issue: Missing dependencies are shown when all of the study type's dependencies are not installed in Dynamo. If the study type runs normally, the dependencies may already be included with the Dependencies folder.
Work-around: If the study type's dependencies are in the Dependencies folder, they do not need to be installed in Dynamo, and you can ignore the warning about missing dependencies in the Graph Dependencies dialog.
Incorrect Sort By menu options in the Explore Outcomes dialog
Symptom: You view the outcomes of a study in the Explore Outcomes dialog. When you try to sort the outcomes, the Sort By menu shows options that don't correspond with the study you are currently viewing.
Issue: This issue occurs when viewing the outcomes of two or more studies in the same session. The Sort By menu will show options for a different study than the one you are currently viewing.
Work-around: Restart the Explore Outcomes dialog and proceed directly to the study whose outcomes you want to sort, without viewing other studies first.
Known issues for Generative Design tools in Dynamo
High-resolution JPEG images cause a silent failure
Symptom: When using Dynamo to create a study type, you specify a high-resolution JPEG file. This causes a failure.
Work-around: Use PNG files or low- or medium-resolution JPEG files as study type images.
Remember node suggestions disappear when you use the custom node pane
Symptom: When using Dynamo to edit a Generative Design graph, Dynamo displays a + icon to indicate where you should add Remember nodes to hold data. If you double-click one of the custom nodes to expand it and switch to the custom node pane, then switch back to the center pane, the suggestions disappear.
Work-around: Close and re-open the graph. If you expand a custom node, do not switch to the custom node pane.
