Another Datum Target Points Disaster Print

Right, I just realized that I can't create a mid-plane for B because I don't have enough points to create planes on each side. I was thinking I could just probe a ton of points on each side of A and ignore the datum target points. It's funny, the engineer is using datum A (and only datum A) for the majority of the FCF's.

I wanted to do an iterative alignment for this program, but I don't understand how I would do that. Apparently you can't use a cylinder as your primary leveling feature in an iterative alignment. I wanted to somehow mix 3D features (Cylinder) and target points in an iterative alignment.

What do you think of this: probe Datum B as a cylinder, level and translate to the cylinder. Then probe a random rational line (the print is almost useless for rotation), rotate to that line. Then key in the datum target point locations, create a line on each side of the part using those points, create a mid-line, and translate to the midline.
