Hi Long-

I’ve posted your workshop videos here:

I made some minor edits to cut out the long pauses at the beginning - when you were setting up - and during the breaks.

Great workshop. This is a generous contribution to the community. Thank you again.

:fist_right: knocks on desk


Nice! Btw I believe @LongNguyen also included some download for the files made in the workshop as well as the PowerPoint / pdf slides. Maybe it is worth to have them there also?

@Michael_Pryor @dan. Thanks for the editing, it is actually much better that way. The accompanying slides and data sets are here!U01SSKCC!S3BZ_oWf9v5KJ-FzwGeU0MkYsy6wtrGt56074b-9Sdg. It would be great if you can host them on your server as my cloud drive bandwidth is quite limited.


Good call @Michael_Pryor

:beers: @LongNguyen!

I’ve uploaded the C#_Workshop_Handouts.rar to our servers and added a download link from


@dan I’ve seen @LongNguyen put newer videos on youtube. Atleast they are in high quality.
I suspect that the content is similar but different :slight_smile:

2018 workshops

Can you update the overview?

The 2018 is 60% similar to the 2017 version. The rests are new materials (Flocking simulation exercise is replaced with Mesh Subdivision Growth (that also covers how to use a third party library e.g. Plankton mesh, and R-Tree). Also the 2018 version covered some important details specific to Rhino 6 (the 2017 version was based on Rhino 5 entirely)


Hey sorry for the delayed response Mathias and Long. I’ll see what I can do about updating these as soon as I get a moment. PRs are also welcome on the developer site, it’s open source :wink:

Ok, I committed an update to the videos page. I can see it live on the WIP version of the page, but I suspect caching on GitHub pages CDNs are not yet updated for the v6 version of the site:

Hopefully they will update soon.
