Known issues for Generative Design in Revit

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Issue: This issue occurs because the folder state is now out of date in Manage Folders.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Work-around: In the Manage Folders dialog, delete any out-of-date folder entries, and add them again.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.

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.

Data.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 Data.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.

Known issues for Dynamo Player

String input in Dynamo Player fails in a graph that contains a Number from Feet and Inches node set as Is Input

Symptom: You edit a Dynamo graph that contains a Number from Feet and Inches node set as Is Input. When you enter a new value for the input in Dynamo Player, the new value will appear in the Player, but the output of the node will not be updated.

Issue: This issue occurs when using the legacy Number from Feet and Inches node.

Work-around: Replace Number from Feet and Inches nodes with Parse Unit Input nodes.
