Mesh Analysis does not display anything I'm trying to use the mesh analysis in the properties panel to inspect my model for the thickness, I want the visual tools rather than the plain selection from the Print3D add-on. However when I check it on, it does nothing. Am I missing something here?

Thanks, Matthew
I use 2.69. I resolved my problem of the Mesh Analysis not functioning when I deleted or, less drastic, switched off the Mirror Modifier. ie, clicked the Eye icon to off.
