I have been going around in circles (no pun intended) to find a solution. When I pack the geometry on a sheet for laser cutting - OpenNest places the circles outside the boundaries of the original geometry. I’ve attached the .gh file and screenshots. Any help would be appreciated.

just nest the external contour-boundary-curve of each shape, and use Transform to integrate the inside curves
if you search the forum you will find dozens of examples exactly like your 
Thx - I will investigate further 
I’m at the PC now in your case something like this looks already enough:
long story short, for each surface take the naked edges and join them into closed curves, then sort them by length and assume the longest one is always the outer boundary (which in this case is always true but it might not be in other cases…)
then nest JUST that boundary, and use the nestring Transformation data to transform everything, also the curves that represent the holes

Thanks so much for the explanation and visual. Its now making a lot more sense.
