I can’t tell from the screenshot, but it is possible that the locations of the problems are too small to see at that zoom level or are hidden behind other objects when viewed from that direction. Internal face edges in particular being, well, “internal” often require that you do something like a section cut or xray view to find them. Surface borders could be anywhere, e.g. on the back side of what you are looking at.
Oh I know, but on the Solid Inspector thing if I click on where it says for instance “Surface Borders” it highlights in the model where the offending things are. Only, in this case, that doesn’t happen.
I suppose this means I’m destined to spend hours going through every single edge inside of the TIN. Yay.
Yes it highlights them, but if you can’t see them because they are too small or are hidden behind something, that doesn’t force them to become visible!
Whereas that is true, it doesn’t cause the problem to become visible if it is obscured in the view. You still need to use xray or to orbit the model to see what TT’s circle is around. Otherwise it will seem as if the Tool is pointing at a completely harmless face in front of the problem!
