Hello to Brian, val2, PILOU and Michael...
I finally managed : ) !!! ..Michael your suggestion to REBUILD curves did the trick. I used #points and set the number to double of the default.
It basically changed the curve when revolved to a SURFACE. Which is what Chipp achieved in his video. (How did he do it without the rebuild command?....)

Thank you to you all for your quick response, much appreciated as always!
Cheers. Sandeep.

I made this
- Copy move the circle's wheel
- UnwrapeCurve by the Michael's Plugin http://moi3d.com/forum/messages.php?webtag=MOI&msg=5136.1
- Extrude the Line obtained
- Copy the module (Array Line)

then Flow
Any problem :)

How many time take your Flow function ?

With above the Flow has taken one half minute
(middle module + little line is your file)

Hello PILOU, thank you for the alternative.
My flow took around one minute to do : )

Thank you again!
Sandeep.

Hi Sandeep, sorry I wasn't able to give you better information the first try, so what you've run into here is the control point spacing of your curve affecting the flow.

If you draw a control point curve and have some control points close together and others far apart from each other, it will make the "parameterization" of the curve also be similarly bunched together and stretched out, and for a surfacing command that preserves the exact structure of the curve into the surface it will mean the UV parameterization of the surface will be the same.

If you rebuild the curve before doing the revolve, it solves it because the rebuilt curve has much more even parameterization.

Hello Michael,
thanks for the deeper explanation.

I will repeat the process a few times, so i get a better understanding all of this.
I am still curious about how Chipp managed to do it in his video, without re-building...?
Any thoughts?

Cheers.
Sandeep.

part 1 : minute 5.25 - 5.40
he made the extrude line surface here from the original surface and no need the rebuild it!

Thank you PILOU. I doubled checked the video.
You are right, but when i rebuild the curve and revolve, it seems to
resolve the issue i was having. Especially since the tyre is now a surface.

I will do this tutorial again and let's see if it works without REBUILDING.

Speak soon.
Cheers.

Sandeep.

Hello everyone! I finally did it! Lot's and lot's of learnings on this one.
Thank you for your help!

Sandeep.

Coming a bit late to this thread, but I'm glad you're able to complete the tire, Sandeep. Your render looks FABULOUS!

Hello Chipp!
Thank you for your response, i tried to reach out to you via your YouTube channel too.

Thanks for the great tutorial!
Cheers.

Sandeep.
