How would you model this pattern into a solid object?

[Anonymous]

So this is the texture 'polystyrene' from the Appereance library. I would like to model it physically into my model. How can that be done?

Hi Kevin,

For this you need the texture as 3 d file (e.g. STL)

Have a look at this tutorial

Can you be more specific in what shape does the surface have that you want to cover with this pattern and how big is it, or in other words how many pattern reputations would be needed ?

[chrisplyler]

By taking irregular cuts out of the object, all over the surface, one by one.

Or by using some software other than F360 that lets you do 3D relief based on a grayscale "texture" image.

That can actually be done by a Fusion 360 plugin called Image2Surface

Whether that's practical really depends on the shape of the object. A surface with strong compound curvature does not lend itself well to the use of this tool.

For such things I'd experiment with Blender's procedural textures and the displacement mapping modifier.

Edit: For example this blobby thing exhibits a true 3D texture and that sort of thing only takes a few minutes to do in Blender. As it is based on a procedural texture it is impervious to modeling updates .

The result is a quad mesh with over 200k polygons that I imported into Fusion 360.

its the sole of a shoe. So a lot of repetitive patterns on a more complex surface

Can I use this if I need to wrap the image around the sole. I have no experience with blender, but I'll try something and see if I can figure it out, thanks for suggesting it. 

[TrippyLighting]

It's not an image, so there's nothing to wrap 😉 Can you share that model from your screenshot ? (export as .f3d and attach to next post )..

If its suitable for what I have in mind I'll demonstrate the workflow.

Thanks for taken that challenge up. Have fun and go crazy with it. 

For some reason I can't attach it. But here is a google drive folder with the file with just the sole:
https://drive.google.com/drive/folders/1LqG89ScZZ9tKPgoB0wmA-Pslj2kx6kCF?usp=sharing

Let me know if you end up needing the whole shoe though. 
I want to 3D print my own shoe with a future/space look, so if the polystyrene isn't working then some moon crater picture is the go to.

Played around in meshmixer, not great but if they other isn't possible then I guess I'll use meshmixer. Anyone know a software that could make a Voronoi pattern on the outer surface? 

[TrippyLighting]

You already used T-Splines to create this model. It seems you deleted some stuff and now there is no T-Spline geometry in the mode that I can use. Can you provide the compete model ?

I would like to re-use the T-PLSine you created in my workflow.

You can share a link to your model directly from the data panel. Right click on the design and select "share public link", enable download (obviously)  and then paste the link here.

1. Converted sole outer surface to T-Spline (had to kill the timeline to do so) and welded seam vertices together.

2. Exported control cage as .obj.

3. Imported .obj into Blender.

4. Applied 5 levels of catmul car subdivision (Subdivision modifier)

5. Adde Displacement modifier.

6 Added procedural voronoi texture to use for displacement modifier and modified parameters to arrive at pattern.

7. Exported quad mesh as .obj (400k+ polygons

8 Imported mesh as .obj into Fusion 360.

9 Converted mesh into T-Spline (takes couple of minutes). This T-Spline is too big to be edited.

10 Converted T-Spline to NURBS surface.

11 Rendered in Fusion 360

**** you did the job no problem. Thanks that's some knowledge. 
I've no clue with blender, but I'll try something. 
I just made the link for the entire shoe if you wanted it still, but guess that doesn't matter now. 

Thanks for showing that this is in fact possible. Thanks again.

Here is the link: https://a360.co/2Jp3bzu

I have another issue in there, I was wondering if you had an answer how I can solve it. The sole and the shape of the shoe can't be combined into one because there is some air between and I don't know how to fill that air out. The problem can also be that it's poorly modeled. But you don't have to fix it, but if you have 2 min would you evaluated how the fix needs to be done so I can try because I'm lost.

The link does not work for some reason.

If you simply for the purpose of this thread delete the linked component of the foot from the design and then export the design as a .f3d and attach it that might be the easiest solution.

I'll create a screencast on how to do this. This might take me a couple of days, so be patient.

it's OK not to know Blender, but if you do this sort of stuff more often than it will be well worth for you to look at.

The Blender community is very responsive there are loads of video tutorials.

The link worked for me. Here is the Fusion 360 file with broken links.

That's odd. Even clicking on the link now, the only thing I get is this (I deleted my email address):

But Thank You!

[lichtzeichenanlage]

Yes - I'm getting a lot in the last ... week or two. Just open the link in an incognito browser (or a browser where you're not logged in) and it should work. You could log off, too. But that's IMHO APITA.

@brianrepp can this be addressed please with the folks that work on "improving" the website ?

I've seen more than one report like this that mentions inability to follow links.

Thanks in advance!

[brianrepp]

Thx, Peter - is this random/intermittent?  Any repeatable way to get the issue to surface?  When I clicked on the link above it, of course :-), opened just fine.
