I created a vase using a Curve and Revolve which I then converted to a Polygon.

Edge rings (Double-MMB click) works fine.
Selection of Primitives and Points also works as expected.

For some reason I can't select edge loops on the resulting geo.

It works fine on a Grid, but I just discovered that it also does not work on a Sphere (Polygon Mesh)

Any help and/or explanation is appreciated.

hi,

did you test the “clean sop”?
