Applying a warped surface normal to a cull pattern

Is there anyway to apply a surface normal to a cull pattern? i am new to grasshopper and am trying to array a tile along a a pavilion roof which has a hyperbolic parabola roof. I am able to get the tile in the correct location, it i am confused on how to assign the normal to the tile. please help, thanks in advance. I will attach grasshopper file, rhino file is too large to attach, but should be able to preview structure from script. Grasshopper file is inherited from a past student, my portion is on the right side of the canvas, labeled TILE SUBSTRATE AND TILING. Pictures are also attached showing the current script and model. Third picture is what I’m aiming for, just want it in grasshopper to adjust individual tile and it array amount easier.
