Issue with PointDeviation not showing any deviation?

2026.01.26 Inner last + outer Last only for testing purposes.3dm (1.9 MB)

Sysinfo.txt (2.4 KB)

I am trying to creat an outer last that will make up the outer surface/shape of a 3d printed shoe. I simplified the inner (main) last and offsetSubD the surface so I have some more control.

Outer last is an open subD, inner last is a closed SubD

Now I need to make sure that the outer last is at least offset 3mm from the inner last at all locations. I can swear that I got PointDeviation to display deviation earlier in the process and don’t exactly know what the problem is now.

Any ideas? Where am I going wrong?
Thank you in advance!
