Recompute whole GH graph?

[user883]

I want a component to restart/recompute the whole GH graph via button or Boolean input manually. so I wonder if there is a plugin or component to do that .?!

Why can’t the user just press F5 or use the fly down menu and select “Recompute canvas”, if they have to trigger it manually?

Triggering from code could easily create an infinite loop if the component triggering it, is itself in the graph being recomputed (and isn’t idempotent, and has no delay).

You can try this:

Rhino- Precompute grasshopper python script

The following seems to be a nice simple way of doing this. If anyone knows if this will cause any problems, please let me know: import Grasshopper as gh gh.Instances.ActiveCanvas.Document.NewSolution(True)

Or this older solution:

Recompute Button

I was just in need of this myself (for a one-click Recompute Solution from the RCP) and ended up here. I’m not sure if this GHPython approach (based on David’s advice above) would be considered super correct, but it does appear to do the trick: def ghSolutionRecompute(): """ Recomputes the Grasshopper solution (ala pressing F5) """ def expireAllComponentsButThis(e): for obj in ghenv.Component.OnPingDocument().Objects: if not obj.InstanceGuid == ghenv.Compon…
