Has anyone experienced errors when exporting STLs directly from Grasshopper. it’s been happening since the previous service release Candidate. I currently have this release installed on Windows 11 PC: [image] I’m seeing the error with both the TT-Toolbox 2 STL export Component as well as a custo…

I tested it, but every time the name of the file changes, it actually bakes inside Rhino. Or if I trigger it with a button (which is what I usually use), it also bakes inside Rhino, which would make the file too heavy. Is there a way to install a previous release of Rhino? Everything was working fi…

After doing some digging, and debugging into the component that kept crashing, it seems like the cuprit was CreateHeadless(). After removing that part and …

You have Rhino 8, why don’t you use the native Grasshopper component to export the geometry? [image] ExportSTL native.gh (16.8 KB)

Yes, I think that is also the way to do it. Use Datatree grafting to create and export multiple blocks to export to multiple file locations if necessary.

Agreed! For simple tasks, the native component is perfect. I developed the custom one because I’m running automated iterations with a sort of counter cycling through design options, where exports need to trigger programmatically based on each iteration’s parameters. But you’re right - for straightfo…
