Incredibly useful feature, this! Excellent!

[@Shenanigans3D]

this will definitely will help with a project I have. thanks for another great video

[@MangoJellySolutions]

Great to hear your finding them useful and thanks for your comments over the lifetime of this channel.

[@antonioiglesias5447]

Thank you again!!

[@donstelfox2936]

Thank you, cheers.

[@sjn8099]

Thank for learning :)

I'd say these features are "normal" to the surface, not "tangent" ;) .
Btw. I would have started with the construction geometry lines as well to align the sketch edges through the arc center. But after the third one you drew, I remembered that you could just have used "point on line". Would have had the same effect without having to draw extra lines.

Nice.

The cylinder placement's Attachment Mode we used is called "Inertial CS" - I don't understand that term. What does 'inertia' have to do with geometry? And what is CS?

[@MangoJellySolutions]

This is the 'axes of inertia' and CS I belive is Coordinate System. Here's a link www.ncbi.nlm.nih.gov/pmc/articles/PMC15493/#:~:text=The%20principal%20axes%20of%20inertia%20of%20a%20rigid%20body%20are,example%20of%20a%20principal%20axis. It explains what it is but the article relates to another subject.

@@MangoJellySolutions Thanks, the article makes it clear.

[@Kotaztrafee]

Wooo, It worked! However, I am finding it impossible to use the same technique to put holes on either side of the existing holes.
Keeps telling me "You can't use population tools on shapes in partdesign body. Use Lattice PartDesign instead. Or deactivate active body to use populate tools on shapes."

I meant, it's a paper-airplane, not really a kite. But well ;)

[@MangoJellySolutions]

Lol, it saves the confusion with plane (kite) and plane (as in xy, y). Can you imaging how confusing that would get.
