i, j, k values for a point

[[La...]]

I am probably overlooking something very simple, but how would I get the i, j, k values for a point in order to probe perpendicular to a plane on an angle.
The A2 Y/Z value is -22.5000
I thought I saw something about this before, and I have not been able found it...maybe on the old forum? Or maybe I'm just not searching this forum correctly.
Thank you in advance for your help.

i= 0
j = sin(-22.5)
k = cos(-22.5)

or try this:
select that feature -> go to "resources" -> features representation -> change mode to "modify" -> go to angle and change to rot-incl vector

I believe that should allow you to input correct angle or it might be the "projection angle" instead of "rot/incl".

I have actually tried Israel's, and Jayesh's suggestions...both worked, but for me using the projection angle Jayesh recommended is simpler for me.

Again, thank you for your help!!!!!!!!!
