Uh, there you go. Nothing.

-Mesh Analysis is activated.
-I am in edit mode, with solid shading.
-Nothing is visible on the model for any mesh analysis tools, at any parameter ranges.
-I tried selecting and deselecting regions of the model.
-I tried closing Blender and opening different .obj files.
I’m interested in using mesh analysis to easily estimate the necessary minimum iterations for Make Planar Faces to strategically flatten out some quads more than others while solid surface modeling.
