Recompute whole definition after running script


i’m looking for a way to recompute the whole grasshopper definition after running a vbscript. In the old forum, I found this post:

Do i have to add something more than “Call Grasshopper.Instances.ActiveCanvas.Document.ExpireSolution(True)” at the end of my code?


May I ask why you’re unhappy with whatever cached data is still retained from a previous solution?

GH_Document.NewSolution(true) is what you need to expire all objects in a document and then run a new solution.

I’m referencing rhino geometry with the elefront plugin based on user attributes. Within the script, I change these attributes to True/False of the rhino objects. This attribute change is triggerd with a button. Last step is I need to recompute either the whole definition or the Elefront Componant which is referencing the rhino geonetry based on the attributes.

I have attached a small example.

recompute.3dm (54.5 KB) (12.2 KB)

I tried your advise but I’m not sure how to use it.
Thank you so much!

Perhaps script the entire attribute referencing and subsequent actions?

that would be nice as well, but I couldn’t find any examples how to reference Rhino objects based on usertext or with the vbscript component.

The less different plugins I need the better.

RhinoObjects store Geometry and Attributes. Attributes hold information about Name, Colour, Material, Visibility … etc.
So whenever you search for RhinoObjects you can also check its attributes for its “Name” and additional UserData.
