<div class=“ytp-copytext ytp-no-contextmenu” tabindex=“1”>What happens when a parameter is changed on the Revit side? I would expect that any changes on the Dynamo side will result in any geometric parameters being changed as the graph is re-run, but non-geometric parameters would be preserved?</div>
