Is that a simple thing to modify in a IKE_HAAS_VF_4AXIS post?

Is that a simple thing to modify in a IKE_HAAS_VF_4AXIS post?

I have only spent a minimal of time in the IKE posts....the changes in it are HUGE and as I have good proven posts, I just haven't had the time...

Now, did you try using a transform?   Drill the 1st hole, use Transform Rotate @18° for the rest of them?

Or...

You can create them on the arc, unroll it, drill them on a flat plane and then use Axis Sub to roll them back up

Couple ways to approach it

Thanks JP

I hawe used transform many times for a simple patterns around the A axis but these holes are staggered along X as well.
I've always had troubles doing A axis substitution but it might be worth giving it another shot.
