Old problem and again I struggle...CAD, Cyl shaped part, alignment

I have a part that basically looks like a Gauge Pin with a hole drilled thru it (90 perp to the longitudinal axis of the cyl).

I am having a very difficult time trying to get this thing aligned using CAD. I have tried 3 points on one of the flat ends, then 2 points along the length, and a single point on "top" about halfway between the thru hole and the nearest end.

Get Iterative Alignment error.

If I dont use iterative alignment, and instead use cir at one end, a cir at the other end, and the thru hole, I can't get the features to "stick" to the CAD.

I've got the part laying on its side inside a R&R AVP 11-20 V-shaped standoff, with the thru hold pointing up, and the length of the part inline with the machine's X-axis.

Thanks folks. I will try some of these. I'll let you know how it comes out. In the old 3.7MR3, I used to have a little trouble with these type parts, but it has been so long since I used it, I've lost my mind on it, apparently.

BTW, I've never tried to change the CAD axis to match how I have it on the machine before. I'll muddle my way thru it, and see how it goes.
