Demotion Pull-Down
The Demotion setting determines whether objects in the modeling window are changed to simpler representations when interactive transforms are performed.
The Refresh button will restore to an un-demoted view. For some display settings/hardware types, Bounding Box is the default setting.
Due to the single-color-per-face display of face data, demotion of boundary surfaces with face data is handled differently. If demotion is set for points or mesh, then the demotion color will be white if the background is black or black if the background is white.
