Making holes in a sphere

Hi Guys,

I’m designing a ball that will have hexagonal holes cut into it. Basically hexagonal depression in the surface. How do I go about cutting hexagonal shapes on a curved surface?

Thanks!

You can simply project hexagonal sketches to the sphere and pish them in.

That works if the ball is hollow with a thin shell and you’re trying to make holes. What if it’s solid, or at least has a thick shell you don’t want to push the whole way through? Doing it as you described would leave an uneven depression. Is it possible in this app to do this with an even depression?

Not sure I get it, but do you mean making extruded cuts to the sphere?

I don’t know if this is what the OP was talking about, but I mean depressions in the surface of the sphere kind of like a golf ball. The extrusions wouldn’t push the whole way through. As you can see in these pics, the depression varies in depth due to the flat bottom.

Yes this is exactly what I”m looking for. So quantitatively
Case 1) Sphere radius 10cm
Solid shell 2 cm (radius 8 to 10cm)
Cut hexagons / other shape from radius 10 cm to 9 cm.

Case 2) Also solid sphere and shapes cut into it
Sphere radius 10cm
Solid
Cut shapes from radius 10cm to 5cm

Case 3) Sphere radius 10cm
Have spikes emerging from sphere (so cylindrical projections outwards) from radius 10cm to 13cm.

These are for a ball design that I am developing so trying to get a 3-D drawing to the mold maker…thanks for all the help!

This looks like a great start - if I wanted to do this uniformly across the sphere - i.e multiple hexagons - how would I do that? Ie. a bunch of uniformly spaced hexagons across the surface of the sphere.

Thanks so much guys - you’re really helpful!

If a completely uniform depth of depression (what I was trying to get at in my first post) isn’t a concern, then yes, it’s just a matter of evenly spacing hexagonal sketches around the surface and then extruding them down into the sphere. I’m brand new to this, though, so I can’t give you any pointers on doing that. If a completely uniform depth is important, I’m still hoping to hear if that’s possible and if so how.

You have to project the sketch to the sphere, then push it in as I said. It will give you the result you are looking for.

That seems like a hugely manual process with a lot of angles and placement issues?

isn’t Shaper able to distribute objects across a plane or sphere uniformly and automatically?
