Quick Check
Quick Check is the fast pass over the plate before printing: select the meshes and each one is checked for construction errors. Sound meshes turn green; meshes with problems turn red. One glance tells you which files are ready and which need attention.

When something comes up red, run Automatic Repair on it — in most cases that is all it takes. For a diagnosis rather than a verdict, use Show Edges to see where the naked or non-manifold edges actually are.
