How Do I Create Hole On A Boll

[RocketNut]

Howdy

I think I did this once in the past, but don't remember how I did it. As shown in the attached screenshot the arrows show the holes (and angle of the holes) I need to place on the ball. Also the holes are all the around the ball.

I would place one hole (perhaps close to the top) ,
then circular pattern it down ,
then circular pattern it around
to ge this: .
Hopefully that helps!

If you need more control, like making the holes more-or-less equidistant in all directions, base the holes on planes that go through the center of the ball. Then you can control the angles and do separate circular patterns with different quantities of holes.
Have fun,

Yes, that looks like it would work. Expect the ball is on top a tub as shown in ordinal post and the X-Axis is at the bottom of the meaning it does not place the holes on the ball.

Just add an axis at the right distance from the X axis!

OK
I am very very red face now. For the likes of me, I can not insert an axis in the ball.

Remember -- if a part is too big to upload just roll it back the the first feature and save it. That will reduce the file size substantially and allow you to upload it. All that is needed after download is to save it to a new location and Regenerate to Last Feature, or the one that has the issue.
Your part went from 10,808 KB down to 398 KB when rolled back to the OuterRing.

Easiest way to insert an axis in the ball is to edit its sketch then select menu Sketch>Insert>Axis. The select the center point/node of the arc, click Apply and Close then deactivate the sketch and rebuild the model. Your new axis should be listed just above the Ball in he Design Explorer.
