Am I making a tessellated sphere correctly in Creo

I need to make a model of a sphere with a sensor screwed into every vertex of a tessilated sphere. My plan at the moment is to calculate those vertices in an external program, import the points into creo, then use the patern tool selecting each datum point. Is there an easier way to do this?

That's how I'd do it.

You could do it entirely in Creo, but it wouldn't be easier or faster. The advantage would be that you could easily change the number of facets afterwards but you have to weigh up if the initial time investment would pay off for the number of times you're likely to change it.

Antonius' information is probably a really good place to start.

But I have to ask how many sensors? 4 or 400, might change the thought process.

Re: Am I making a tessellated sphere correctly in Creo

40000

I don't think Antonius' method would work. Maybe this is something creo just can't do.

I have the points in creo, but when I pattern them, they point in the same direction as the first hole.

There so many sensors for this to work.

Re: Am I making a tessellated sphere correctly in Creo

Yeah, see, that is some key information right there. And how big is the sphere going to be?

Re: Am I making a tessellated sphere correctly in Creo

There is an option in the fill pattern that used the surface normals. Unfortunately, for a point pattern, points have this information built into them. I have had this issue before where we do not have good control of how the points are defined internally. I've had similar shortcomings with splines where you expected the normal to "twist" but didn't depending solely on how they were generated.

I maybe giving too much information on the product. Bigger then a workout ball, let's say. Fairly big.

Re: Am I making a tessellated sphere correctly in Creo

Fill patterns, hmmm, let me look those up. I'll get back to you.
