This is Crystal Clear, you really went into the most important details using patience and time, and this is exactly what's needed to grasp those concepts. Thanks!

This is by far the best explanation of list management if Grasshopper I have come across, with simple but effective examples. Thank you and keep up the nice work!

This MUST return. It's way too awesome.

Simply amazing, congratulations! Finally an explanation that rocks! ...two thumbs up.

Excellent tutorial. I like all the detailed explanations and examples. Very clear.

Thanks for sharing! This is helpful even after years of using Grasshopper!

Wow this is amazing!!! I really like the clear explanation and how you actually show how the data looks!! I was very confused about lists and how/why you would use the flatten graft and simplify tool.

Helpful explanation, thank you!

Thank you for this great explanation You were using the term 'group', which is simple and meaningful Usually in the Grasshopper community, they use the term 'list'

thank you

Thanks.... 👍

Very helpful bro.

Thank you very much :)

Thank you so much for very clear and helpful explanation. Can we use flatten on a deconstruct brep component applid on a group of elements , to isolate one of them?

Awesome...thanks

finally I understand what flatten and graft are xD

thnx

thank you !

Thanks you

thANKS A LOT~

that was helpful :)

wow!!

hey p.h which program do you use to type/drawn in the screen?

nice~~~

What do you use to zoom and annotate screen?

i have been looking for a while how u automatically show the grasshopper command name at the top of it when put it in grasshopper? is it using another plug in or just settings? this video is really helpful, thank you

hey, I really appreacite your work. I was thinking to get a 3 months plan, but monthly payments of 30+$ would be better for me than paying once 100$. Have you considered to enable payments in monthly instalments?

Can you, please, explain what is the Path Mapper component, what is used for, when we should use it ? Thank you.

Very informative, thank you, Perhaps a bit too quick with your ability, overpowering the time it take’s to see what you just did and how! Thank goodness for pause & rewind

hey, these options when right clicked are not shown for me.., only preview, enabled and bake is shown, can someone tell me a solution to this 🙂

How to show the name of the component above the component? Ex. word "Point" above "point component"

:)

tks it was such a pain to understand graft and flatten

This was not a help because rhino six works a bit different when it comes to the loft command

Wouldn't it be better if you used the term "paths" & "branches," instead of "groups"...? There are just enough visual context clues to follow along, but I witnessed new Grasshopper users who had a tough time following along during the "flatten" & "graft" demonstration of your video. The offical Grasshopper help documents & Grasshopper UI itself use the terms "paths/branches/data items", so they found it hard to follow along as you tried to explain data items ("leaves") & branches as "groups" (e.g., @10:12). It did not help that the video kept repeating "groups" when there's a frequently utilized Rhino command, "_Group." Your videos are generally helpful, but using proper/technical terms (b/c Rhino & Grasshopper are very technical) & being succinct with your words could avoid further confusion to other viewers out there as well.
