I installed the MeshToolkit Package (Version 1.0.0), but after it installed, I’d get the error below, and the package wouldn’t show up on the left hand side like all the other packages. It shows up under “Manage Packages” (in the image below). I tried running it outside of Revit, and I still don’t see it. I tried uninstalling, reinstalling, and restarting my computer, still no luck. I tried installing Version 0.9.0, and I still can’t use the package.My Dynamo add-in says it’s up-to-date (Version 0.9.2.4472). Do you have any idea of what I’m doing wrong?

Hi Joel,

You need to install newer verion of Dynamo version (1.0). You can find it in download at the page below. Good Luck!

I’ve had the same problem. But installing the older version (0.9) seemed to work. But it’s frustrating…
