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!
