I’m new to Dynamo, and not sure if this is a bug or if I’m doing something wrong. Google search on the topic reveals nothing.
If I create a new .dyn and use the Levels.Selection node, all is well, the output shows a Level from the model with it’s name and elevation.
As soon as I save my work and re-open that same .dyn later, the levels are still available to select from in the node dropdown, but their output value shows as null. Changing my level selection and replacing the node make no difference. Only starting another new, blank .dyn file brings back the Levels as anything but null.
