How to wrap a fractal around a cylindrical surface?

amszabo — Tue, 07 Jan 2025 03:20:49 GMT

Hey, everyone. New Autodesk user here. I am trying to make a fractal magic wand which entails sizing the fractal to 1.5mm and wrapping it around the cylindrical surface of the wand up to the part of the wand that has the washers on it. Can anyone teach me how to do this?

My first advice, just based of hearing your request is to use the emboss tool to wrap something, but I'll give you some better advice and share a screencast once the file opens for me

*First question from me, because you haven't named anything and sketches don't exist here...

Your trying to scale the meshbody 1 to 1.5 mm and wrap it round the wand skeleton structure to make that design, because if that's the case there's a simpler way

Do you mean like this?

As a new user, the worst thing you can do to learn Fusion is to download stuff you don't understand and try to modify it. My recommendation would be to go through the self-paced learning tutorials and learn the basic concepts of CAD modeling with the software:

The objects you imported are miles away form the origin, which is not good at all.

As you are working with imported geometry, by default you are working with the timeline disabled.

The very first thing I'd do before enabling the timeline is to use the point-to-point move tool and move the objects to the origin.

That is correct. I am trying to scale the meshbody1 to 1.5mm and wrap it around Body1 (the wand) at all points just before the circles near the base of the wand.

Yes! That is exactly it. How did you do that? Are you able to wrap it around the entirety of the wand to just before reaching the circles on the wand? ( meaning that the fractal is on the entire right side of the picture below and stopping at the circles)

It was just a first try to see if I understood and perhaps I still don't!....Which area? and what is the purpose and how will you realise the design 3D print?

The blue area is where the fractal goes ( the entire area in the new picture). This is intended as a wizard wand ( also for cosplay!). I am thinking that I will CNC it as the details are pretty finite in this.

1. What you have, is a skeleton...

2. It needs to have an outer surface to do what @Warmingup1953 did.

Here are the steps to follow, as using an imported skeleton structure isn't the greatest way to learn or go on with this project.

1. At the back end of your skeleton, make a sketch, where you draw a centre point circle that alligns with the wand skeletal strucutre, 2. extrude, it to the end of the wand where it becomes too thick to go to the next section.

2. This leaves you with a solid body which can have the emboss tool used on it.

3. Select the emboss tool, select both the newly made cylinder and the design ensuring that the design is wrapping the cylinder, change emboss settings to engrave, and watch the magic!

4. The rest of the wand forward from there can just be done via more circular sketches extrusion and fillets, with a few chambers to get the rigt shape!

Would it be possible for you to make a video for how to do that? I am very new to Autodesk.

Hi Mr AmSzabo,

Look at the phrase:

“Cookies and CADmen are the best friends, aren’t they?”

in https://forums.autodesk.com/t5/fusion-design-validate-document/any-help-on-how-to-sketch-this-please/m-p/9239917#M205019

You will find the plane-cylinder homomorphic transformation example/formula there.

The fractal magic wand is a low-level 2D Hilbert curve, a widely known ‘mathematical wonder’ described by a ‘trivial’ recursive formula.

How to add a Hilbert spice to the cookie recipe?

I see two options on my extreme right and extreme left.

Apply/merge the Hilbert equation with the plane-cylinder homomorphic transformation formula. Some mathematics and programming skills enhanced by F360 API could make a design miracle.
If you have slept during math classes or are still too young to be effectively tortured by Math Teachers, do the following.
1. Gather the curve’s point coordinates (on a sketch) of the Hilbert curve
2. Calculate the respective point’s transformations (for a given cylinder radius)
3. Transfer the resulting points to a 3D sketch
4. Connect points by line or arc segments reflecting the topology of the original Hilbert curve.
5. Do some postprocessing with the resulting sketch path
6. And … it is almost done … unless
7. You want to check the strength of the magic …
8. Spell your abracadabra and perform a voodoo dance.

Firstly @MichaelT_123 You have apparently been away from school from too long because MATHS is tortuous at all levels, and as long as math teachers exist, I ain't never gonna get the last hour of the 8 hours of sleep I need a day... And I am utterly dissapointed in you, he's new, your meant to be harsher, what would Hon. Pirxess and Pirx say to that, I can't imagine their horrified faces...

But for @amszabo Unfortunately, I'm experiencing issues with F360 and my recorder (OBS) so I'll demonstrate via screenshots...

I'll have attatched it within the next 30 minutes as I am at that age age where I am "effectively tortured"

Pixie 👿 regards

Goodnight @amszabo

READ THE WHOLE THING FIRST, MAKE SURE TO CONSTRAIN YOUR DESIGN ALONG THE WAY UNLIKE ME AS I RUSHED AND START WITH A SOLID BODY, NOT A HOLLOW LIKE HOW I STARTED, YOU'LL UNDERSTAND WHEN YOU'VE READ EVERYTHING...

First made a half side profile sketch

used the revolve tool to quickly revolve sketch (Mine is a bad example as I'm not taking dimension/looks into consideration, just thinking as a quick example)

found in surfaces section...

thicken, (left inside hollow, in case want to put something inside while cosplaying to shoot out of wand...) *I TAKE BACK WHAT I SAY, FILL THE FULL INSIDE

Fillet and chamfer and chamber as required/ wanted for your specific shape, or shape the starting sketch much better actually...

Just a quick offset plane in construction bar

just a quick sketch on that offset plane.

Use the emboss tool, and deboss to engrave it into the wand handle. (Right hollow the wand at the end, I didn't realise engrave doesn't worked on hollow bodies...

This creates an engraving on the handle...

I think you should've accepted to make a proper "true fractral wand" as it isn't possible unless your refined accurate and Idk's where our refined accurate guy is so yeh... But your best bet, is where I made the sketch, make a close as possible sketch of what you want to engrave on the wand and then engrace it. (I hope you can do simple maths, so find the diameter of the wand handle, and make sure the sketch is exactly that height so it all matches up and looks good)

Sleepy regards

Ricky

All fantastic responses. Thank you all so much!

Hi Mr AmSzabo, Mr TimelesslyTiredYouth and BoredOthers,

For some mysterious reason, the post popped up on my screen while I was searching for unrelated topics.

I read it with interest (including also my part) and … as I could not ignore the mystifying omen … decided to release for protection some spells from my chest of visuals.

I will expound on them in a separate post (with the title starting with “Hi”), accompanied by the somewhat related, somewhat philosophical narration.

(Warning: smoking something, without inhaling, of course, is recommended ... before reading it! )

Regards
