Can you make a ball with extrude boss?

[ponxerino]

Recently i had this question on my mind, can you make a cube out of revolve boss feature in solidworks,

, which i was able to do with 1 revolve boss and 1 circular pattern, 4 shapes that make the total cube, which begs the question, can you make a Ball out of extrude boss?

[Nate_Laverdure]

Sure

[ponxerino]

I agree that this is a ball, but it doesn’t like a smooth ball, i assume the simplest way to do it is just make a circular pattern with over 9000 instances, but it wont look like it was made with revolve boss, compared to the cube i made with revolve boss.

Incidentally! This observation is related to why the lathe is the king of the machine tools, able to progenerate more lathes and mills.

[DonRotolo]

Yes indeed.

The only part of a lathe that can’t be made with a lathe is the bed, but that’s just a flat plate.

Smaller flat plates, flat to better than 1/10,000" can be made on a lathe, and these used to fashion a larger flat bed.

Which begs the existential question: which came first, the lathe or the egg?

My Attempt.

A bit cheeky, but I did it with two semi-spherical surfaces and the up-to-surface end condition

Are you allowed to use the fillet tool? Or is that too easy?

[A_Reed]

I suppose that works as well.

[Andrew_L]

That’s how I usually do it.

Want to show us what the sketch is?

If the rules are “no revolutions and no fillets”:

Surface-Fill1 is doing the heavy lifting here.

You can totally do this without the circular pattern and mirror as well, you just have to do each corner one by one manually before stitching.

What, you don’t download your balls from McMaster-Carr?
Come on.

ummmm

[Domtech]

What about patterning 180 cylinders and then taking the intersection of them:

Very pretty Moiré pattern!
