I am not sure if this is a bug or just me missing something. I have created a 3 D component of a veterinary symbol and when I set up the preview toolpaths and run them, some of my tabs don't show on the preview. I have two internal tabs that do show but the ones I placed around the outside of the component do not show in the preview. I am using the latest version of Aspire 9 on windows 10 system.
