Anyone have thoughts on how to process "best fit" hole patterns on oddly shaped parts?

Anyone have thoughts on how to process "best fit" hole patterns on oddly shaped parts?

I am thinking about some different methods, but maybe a fresh approach could
get me off center!

Thanks, I will also share final approach when done.... 🙂

1. Compare areas.
2. Divide into segments and sum the offset distances, or use any statistical evaluation method.

I am going to try to create multiple hole
locations, then check the total distance between them....

Hopefully the hole pattern with the greatest total
distance will work.... 🙂

You did not state the type of entity that represents the hole like shapes.
If periodic points along the perimeter of the 'holes' can be derived from the objects,
then you can also derive a list of centers from the intercepts of the normals at the midpoints on two consecutive cords.
A pseudo center can be made from the centers list by averaging or by some statistical method, and a a radius likewise.
For design purposes, the center location and radii dimensions would be standardized.
