Code block functions and the Primer

Trying to write some code block functions and having trouble with the example in the Primer (About | The Dynamo Primer). Has anybody used this example successfully? I downloaded it and am not getting the results shown in the primer. Not sure if the downloaded example is a completed version or a starter version.

@AGR - Have you set the Lacing on the node? Right-click on the node, and run through the Lacing option, and choose “Longest” as is on this example.

If you are in a Dynamo version beyond 2.0, it should be on auto lacing and correctly show what you want to see here.

Thanks, solamour. I went back through the example steps without downloading the dyn file and it worked, so there may be something off in the dyn file provided. Also, the example recommends using Cross Product lacing, so I tried that and also Longest lacing. Either way, my results are slightly different, but at least the example runs now.
