Rectangular Based Pattern on Tower Facade is not perpendicular to faces

Hello Everyone!

I have created a tower that has a rectangular based pattern that has a culled pattern (mix) of these solid rectangular panels with these extruded trapezoidal openings. The problem is that these trapezoidal blocks are not perpendicular to the face. I'm using a list item component to break down the blocks to their points and create a relationship to the twisted box so that it adheres to the other adjustments I've made on the tower.

I was wondering if anyone could help me figure out a way to get these trapezoidal blocks to be perpendicular to the surface so that the smaller end of the block is extruded out and the larger side is on the face of the tower.

Thank you so much for your time and effort to help me figure out this problem!

Sincerely,

Alexandra
