Are you looking for random or are you looling for pattern.

Also - your part isn't spherical, but it looks like maybe you intended for it to be spherical.
The R40 arc center point isn't on the axis of revolution.

 

If you are looking for a pattern - then curve driven pattern might give you a solution.
If you are looking for randum - there is no Easy Button, you will have to simply start creating pierce points (I didn't check Curtis' post but I assume that is what is demonstrated.

I suspect there might be a way to caculate random points on a sphere (if you had a sphere) and bring them in from an Excel spread sheet but I don't know what the equation would be.  If you find one and need help in getting holes from the points - post back.

Hi petdem, 

 

You can use a work axis to define an intrsection point, and then use the point to create a hole, as described at this link:

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

Yes you are correct about th sphere .I have corrected but my computer is down .ALso the solution button was accidently hit as I am using my phone for this reply.Yes please help on the points and excel would be great.ALso help on curve driven pattern is also new for me.I hope my computer will be up and running again soon.please keep in touch so I can learn these 2 new concepts

The corrected file is attached.I will look to use patterns A sample picture is attached.My problem is how will i get the holes at the correct angle as i move the pattern of holes towards the ends of the sphere.The number of holes also decreases as the pattern moves towards the ends of the sphere

inventor 2012 file attached and a picture of the hole patterns i need to model

OK,i attempted to add the holes using the circular pattern and mirror features.I was not very successful in getting the holes in the correct angle through the sphere.I need some help on how to do the following

1. how do i get the holes at the correct angle going through the sphere

2. how to have even spaces between each circular pattern feature as i move towards the top of the sphere

 

I`m sure one of you much more experienced users would have a better way of performing this then the way i created the holes.

 

I have attached my quick example anyway

 

Pete
