Hey Everyone,

I'm trying to make sense of what Surface Borders and Internal Face Edges mean, and how to fix them

In my model, I have pieces that intersect, and I am chopping off the parts that intersect.

I traced lines around the edge of the intersecting parts, and then deleted the overhanging parts.

When I use solid inspector 2, and I am getting these errors in cleanup.

How do I resolve the errors its telling me about?
