This part was model using 2D sketch in the video. Do you have any idea of modeling this using 3D sketch only. I think using 3D sketch is simple. I tried but unable to proceed.

If you can't do no one can do.
Your 3D sketch is wrong. This object have only one contour loop. This is correct:
I modeled this with one 3D sketch.
March Madness
As you always say, post your model
I meant that it is impossible to model this object as one (two) operation, i.e. the surface and its thickening.
Of course, in many operations you can. For example 6 features (including sketches, planes, axes)
Maha Nadarasa, I'm not sure why you think this has to be done using a 3D sketch but here one way to do it. I'm sure some will think its not the best way but it meets the requirement of having just one 3D sketch.
This is the sketch of the model but everything was done in 2D plane. This is what prompt me to think 3D sketch.
"I'm sure some will think its not the best way...."
And the best or better way is?

I see two - 2D sketches in your tree.
The challenge was having just one - 3D sketch.
Hmmm... where is your tree?
But if you say "challenge" - OK, I like challenges.
I little fix my previous model - four operations:
The model is geometrically correct:
File please.
where is the axis of your pattern?
In the screenshot above, the pattern axis as well as all other definition is in the sole 3D sketch.
I got it with just one feature and 2 3D-sketches. May have cheated though
hello,
this part seems to be a little "modeling exercice-pratice"
in french i would call it a little "exercice de style"
here is a picture,
(i used a little sketch cheat ...)
but i think it's possible to avoid it (the little sketch trick), but it will be more than one feature...
File please.
Sorry, i can't access the file now, because of the "Outbreak" confinement.
But i think Mark Dougall find the same solution like, maybe he can give his file.
except i begin create tree with 3d sketch, and use some "temporary 2d plane" inside,
to close the path, you may need to "cheat" a little, because
if you add "equal length" to every line, you get an error to the end, while closing the path itself.
also the cheat of not using a dim "XX" at one place, and use the cheat of "XX.001" to avoid geometric failure.
and i only used a 2d sketch for the Sweep, because i used a "temporary 2d plane" (from the 3d sketch) to create the 2d shape sketch.
and to finish, in the "Sweep" option panel, i activated "Merge Tangent Faces"
Impossible make in one operation. Its the same as Mobius Ribbon.
But no one can forbidden to try you. Some are still fighting Perpetuum Mobile.
