Help with cutout design on a sphere?

[zimmen84]

Hi all heroes!

I need help to make a design cutout on a Sphere.

and then I would like to make the sphere in to 4 different pieces, something like attached photo.

I have used Square in the Screencast, You use similar shapes, And you can get the shapes...

Once you create the Hollow Sphere, just sketch random shapes... 

And before that, create some planes at angles, and sketch on all those extra planes...

Hi,

I think, Voronoi is what you are looking for

Hi,

Maybe Voronoi Sketch Generator  (Fusion AppStore) will become your friend.

Huge thnx, but not exactly what I need.

If you see my attached image you will understand how the 4 segments of the sphere is.

The four of them will be joined together to bring them together into a sphere.

So I need a way to put patterns like this (just bought a bunch) see the picture I attach.
This pattern should be across the entire sphere so that they join at each segment.

Did you see my last reply?

[zimmen84]

It was a nice tool, but not for me, the edges gets a bit ruff, and i need clean edged because it will be lasercut on acrylic

[rushabhthakkar_910]

Yes, I have seen it... Message #11. Was there anything I was supposed to notice... But skipped..??

That pattern has holes and islands that fall out.

Sheetmetal wrap, will get you nearby, but the pattern will need the internal ball to glue the islands to.

Might help....

Dude this looks almost like the thing I need?

If you see my #3 post, You'll see it's just the pattern I want to keep in the sphere. 

Ps. Can you make a Screencast of how you did it? 

[rushabhthakkar_910]

No Doubt @davebYYPCU has done an amazing Job. But he has also mentioned it will need a inner solid body to glue the islands... And your's is a hollow one.. 

If you are okay with the sphere being a solid, than I guess it's good for @davebYYPCU to make the screencast.. 

[zimmen84]

It should work just as well, I think? As long as I can take DXF out of the correct one, I should be able to cut them in the laser. 

He's onto something now, so maybe we'll figure them out. 

[davebYYPCU]

What thickness is your material, and diametre of the sphere required, and width of petal strip?

I did it with mirror segments, and the small segment will be okay with hollow ball I reckon cause there would not be islands with this pattern.  (I got islands with first attempt debossing, instead of embossing, - sorry if that was confusing)

Screencast and I don't get on, but can refine and send a model, when I know your sizes.

[zimmen84]

Well I was planing to laser it in different materials, 2 & 3mm steel, and 5mm acrylic.

The biggest diameter is 600mm so it's quite big.

The petal stripe with approx. 5-8 mm

[davebYYPCU]

Ok, 600 x 8 x 3 mm to the outside,

The tricky bits, 

Working backwards down the timeline, all the panels were combined to one globe.

The globe is divided into 6 panels, better chance of compound bending, (over a 4 panel effort,) and your flower seemed to work better for 6 panels

These panels were built with 1/4 being mirrored twice.

The flanges are unfolded, move to the solid modelling area to cut extrude etc, when done refold in Sheetmetal.

The temporary body is made by a trimmed ellipse, 15 degrees off horizontal, extruded thin wall at 8mm and nominal thickness, (only needed to make an emboss outline, for dxf and extrude cut the waste off the flange.  Split Body to trim the folding portions off it.

Save Sketch 4 as dxf and edit / trim the unwanted sections.

Cut 12 off front and backs

Step up the timeline, ask questions.

Might help....

OMG Dude, this is so good. You did a hell of a work there!

So grateful of the time you spent and your work. 

But its now exactly as i want it, its darn close I can say

I see that you did a modell of the flower pattern, what I would like  to do is to be able to use different pattern of the ones I bought ?

So i can choose different depending on what i need.
