Sketch driven pattern on non-planar surface

Question asked by Sam Thompson on Dec 9, 2018

I am trying to create a wing section with a series of 18 'pressure tap' holes running down the centre. The holes have to be perpendicular to the face. I have the first hole, created by making a constructing line tangent to the profile curve, making a plane and using that to draw the circle.

I have tried to use Curve Driven Pattern which gets the holes to be perpendicular but the are an irregular distance along the profile. I have also tried Sketch Driven Pattern which gets the holes in the correct location but not perpendicular to the face.

Can anyone think of a function/process to get irregular holes perpendicular to the face? Pictures are attached, hope it helps.

Thanks in advance,
