In attempting to make a graph that will check to see if a space is properly bounded by the ceiling of a model I have made the below graph. (I was working with a couple methods but have frozen all but the bottom section to isolate it) In the instance of the first listed space, I intentionally set the height very low so that the volume would definitely change after the height was increased as it would be well below the ceiling. I am able to see the change in the height of the space, but, for some reason, the volume that Dynamo is pulling does not change after the height does, even though, when I go back into Revit after the graph runs, the volume is showing as having been changed. My question here is this: Does Revit update related parameters (in this case, volume related to height) while a Dynamo graph is running, or does or does Revit not get control to do that until after the graph has finished running?
Thanks for any help.
