Tunnel Through Toposurface

Hey Guys

I’m very recent to using Dynamo , howvere have used lots of grasshopper in the past.

Am currently following a video online : https://www.youtube.com/watch?v=PJHKts9QqIw

Once i get to the stage in the video my selecting my toposurface , in the mesh faces vertices script component i get " Custom node definition is not loaded"?

Any ideas to fix this


Hi - To clarify it means the node has to be downloaded from the Package Manager - Use the Packages drop-down menu to download & install that node from the Clockwork package (Usually the author of the video would mention the source of the package)
Hope it helps!
