How to see the the Diagnostic/Check problems on the mesh display?

Using Rhinoceros 6, I did an Analyze/Diagnostic/Check and it shows me all the problems with the mesh (naked edges, intersecting faces, degenerate faces, etc), but I can never figure out how to see them on the displayed mesh. Please advise. Thanks.

Use the MeshRepair command.
It will step you through finding and fixing the problems.

Hello- use ShowEdges for the naked and non-manifold edges. Self-intersections are not possible to see in V6 .
