Hi all,

anybody has an idea on how to model this in my favorite, one and only 3D program, MOI?

I am at a loss on my end... This guy did it in Fusion. (https://www.youtube.com/watch?v=9NtoOdXWzEk)

Thanks!

The process is not very hard.

First you draw a cylinder (ex: diam 4mm and height 55mm)

you draw a line cutting the circle in the middle.

You do a boolean between cyclinder and line.

You draw line from the center at bottom to center at top of the cylinder

You make Deform/twist on your 2 parts of cyclinder using the middle line as axis of the twist and you use 1800 degrees for example.


Draw the Cane as a curve.

Last step is Deform Flow of your 2 parts of cylinder using middle line and the cane curve as source and target curves.
Check on the Stretch option to adapt your candy cane on the cane curve.

If you want an example file, I could post it too.

Have fun !

I found a link on the model I made 4 years ago... HERE...

You have maybe more speedy! :)
Save your fusion file in format Step or IGES
Reload it in Moi3D! :)


if your file was in the free Onshape online the format 3Dm will be more easy for import export with Moi3D! :)

Else another method ! :)

Screw (Twist)

Then Flow as Phiro said (and give any form you want ! ;)

After watching the video, I just had to try it in Moi.

Didn't think about Flow to deform. I tried to do it with twist alone, twist didn't do the curved part right...

Is twist only for straight parts/objects?

Thanks to both of you, this looks like the way to do it.

Thanks again! Much appreciated!
Can't say enough about the forum here and its members as well as MOI.

Just love it!

In practice, I would prob create the pattern using uv's (by simply offset the coordinate in your DCC/render software).
But if you want to build it as geometry, you can also use the flow deform, that can act like a uv conform operation.

You need the pattern, as source surface (a simple plane), and a sweep tube (with no cap).
It's better to resample the curve use for the sweep to create evenly point distribution (rebuild command).

Actually the hardest part is to find the right position on the surface when building the flow deform.
You have to pick the pattern, the source plane, then the target sweep surface, but depending where you click, the pattern orientation can be tiled, it's not always easy to find the right spot.
(I wish we could change the direction in the flow option instead to redo the 3 steps operation over and over)

We want to eat that! :)

A while ago, I added the "SwapUV", "FlipU", "FlipV" and "Update History" options to the flow command's UI for the same reason. They were documented for the scripting but not used in the UI, I guess for ui simplicity.
I'll attach it here

Ho now that's super neat, I new the few hidden commands, but I didn't know some parameter where also hidden in the interface. Thanks a lot for sharing this !

Flow command was yet some powerful, now it's a monster of power! ;)

A nice way to model the part.

Another thumbs up for the extra functions in Flow.


Thanks to both of you.
Martin.

@ Mo
In what folder must be placed this extra Flow Options ? In commands ?

In fact Both Normal folder Moi /commands Roaming folder / Moi / Commands

Hi,
I've replaced it with the original "Flow" command, but if you want to keep the original, you can rename it to something else (for example, "Flow2.htm" and "Flow2.js"), place it in the "moi appdata commands" folder, and assign a shortcut (for example, Shift+F=Flow2). This way you don't need to replace it with every new release.

Perfect!

Super cool! Also thanks to MO for the updated Flow!

I'm seeing the Update History but not the Swap and Flip UV commands. Are these commands available somewhere? Thanks for sharing this Mo!

Hi danperk, those other options are only applicable for surface-to-surface Flow.

In your screenshot it looks like you're doing a curve-to-curve Flow instead.

Ah Thanks Michael, got side tracked by a candy cane! This is great, I've lost track how many times I've manually updated History for this kind of stuff.

"ExtraFlowOptions.zip" Thanks Mo for this! Flow is indispensable to us Jewelry Designers! :)
