Is there a grasshopper document property I can set (say when a custom component solves) to force a recalculation when a rhino document is opened or a new document set? This is regardless of whether the grasshopper definition references any document geometry objects.
If your working in a custom component, why not just use a Rhino event watcher for that? I think even in a script component you can have a class in the "additional functions" area, so you may be able to do it there as well..
