If problematic location causes meshing to fail, Workbench alerts you by:
Displaying a Show Problematic Location message annotation in the Geometry window
Displaying messages in the Messages window to describe the problem
Note: When the problematic location is inside the body, you can use wire frame mode to visualize that particular location.
