Does a placed 3MF rotation change the downward-facing area before analysis?

Transforms come before the screen

Translation alone does not change a face angle. Rotation can change which triangles point downward, and non-uniform scaling can change normals and angles. Declared-unit conversion changes physical area but uniform positive scale does not change angle classification. A low or zero flagged result does not establish adhesion, bridges, islands or general printability.
