what method do i use to place random holes on the part file attached.how do i place the holes with the correct angle?I`m unsure on how to perform the task of placing the holes randomly around the part with correct angle.how can i do this please for 3mm holes?
Solved! Go to Solution.
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.

sorry i did not explain very well.i reattached part with hole.how can i now scatter holes all over the ball region.maybe about 50 holes randomly scattered around the ball region of the part.thanxs
Please how can I create this pattern
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.
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
