My definition scans the whole Rhino file for blocks and their attributes. This can take a very long time, specially because I also measure volumes, areas, centroids,… When I open a new Rhino file, I get error messages such as this one : [File swap rpoblem] (I get a similar message for the standa…

This could be your recompute component. author = “david.mavrov” version = “2019.10.01” ghenv.Component.Name = “RecomputeSolution” ghenv.Component.NickName = “RS” if Recompute: def recomputeCanvas(e): for obj in ghenv.Component.OnPingDocument().Objects: if not obj.InstanceGuid == ghenv.Compon…

Hi David, Thanks, but what is this ? Python ? VB ? People who ask silly questions like me can’t tell the difference, you know …

This is Python. All you need is a button to make it work. What is missing is code to look for when a new file is loaded and output a short “True” boolean. Basically this will be your first component, the trigger will be a second one. (Don’t worry, I can’t tell the difference either :D)

[image] davidsmavrov: What is missing is code to look for when a new file is loaded and output a short “True” boolean. David, this is the real issue. Once I get a trigger for when the file is changed, I can expire a root component in my definition with Metahopper for instance.

I know. But at least you have a solution for one part of the problem. I will try and find the other part of the puzzle, but it will take me some time. With a bit of luck someone on the forum knows how to do it. Here is the component if you have issues creating it. recompute.gh (1.6 KB)

I think we need a second David here… @DavidRutten It would be great to have an official GH component that serves as a dynamic flag for when the Rhino model is changed.

Found something old… But I don’t remember what we did here exactly. Let’s give it a shot… [image] Recompute solution if a new file is imported Grasshopper I can´t make it work… What am I missing? I copy pasted the code in C, but when I open a new document it d…

Try this! recompute2.gh (2.5 KB)

You can also call this method: [image] Rhino- Precompute grasshopper python script Grasshopper Developer 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…

[image] davidsmavrov: Try this! recompute2.gh (2.5 KB) The C# component does the job, but I realize that expiring the solution isn’t enough. There’s a lot of data that remain stored and needs to be flushed. What would be really great is if the output “A” could briefly send a “true” boolean…
