Profile of surface

Looks like you need a plane with at least 4 points for datum A (6+ would be better) then a Circle for the diameter of datum B, and a line or plane for datum C.

When I do that, it says first and third plane axis are parallel and it won't let me get the measurement

Are you doing it like I mentioned in my post? They should not be parallel, but perpendicular. Are you using the face with the Recycle symbol for Datum A? It is showing the side of the part, but the datum triangle is pointing towards the face. Similar to how C is showing the other face of the part, but the Datum triangle is pointing to the "left" or away from the face, to the side of the part.

Yah I'm lost too... Those should be perpendicular. 
Post your code.

I did exactly as you told and with or without alignment it says they are parallel.

your theo vectors of plane2 are wrong.

What should I put there?

1,0,0

When I do it, it works but my dimension is 0.000

you should remeasure your datums after your manual alignment and make a new alignment with your dcc datums. you also need to scan the hole contour on several levels not just the one radius.

So do my datums manualy, make alignments than do them in dcc mode and do new alignments?

yes
