Looks like you already did it.
So you probably:
Leveled to a plane Z+
You made an XY origin (C1) circle
Rotated about a generic line (X axis) you made @ XYZ 0,0,0 and IJK 1,0,0 and length of your choice
C1 --------- generic line -------------
> OR:
a line you construct by point from C1 to a point you constructed from an OFFSET point (C2 offset Yminus by value of A)
But sequence to make your alignment (ALN) is:
Level to Z
Rotate to X plus about Z plus using Rotated line created above.
(I am probably very confused about your question)
