I have been working through the vent example on the Onshape learning center and cannot find where I am going wrong with my variables.  It may be an issue with my geo constraints as well but it seems as though my circular pattern 2 keeps moving my construction lines away from where I want them to be.  Any help would be greatly appreciated!

Be sure to pay attention to the hints in Step 9 and Step 12. The entities you constrain with the geometric sketch relations really matter on this exercise for the pattern to properly build.

@KatieHuffman thanks for pointing that out, but i still can't manage to keep the vertical construction line concentric with the center...
Do you have any sugestion on which feature should I select to improve the result? I've rewatched all the courses related to constrains & sketches, but I'm missing something...

Exercise 31: Vent | Vent (onshape.com)

After asking the question i finally found the issue....

I'm leaving the part available to show the encountered issue and the solution (in 2 different versions)

@mirko_rener I'm having the issue shown in your example version but I can't tell what the difference is. Something in sketch 3, but they look identical to me, barring the fact that the slot width vertical in step 12 is tied to the horizontal construction line in one and the point of said line in the other (it makes some change but has minimal effect). Are you able to describe it?
