Move Down Sequence, Move Up Sequence

These functions are mostly used with splines; hence, you’ll also find these functions on the Structure > Edit Spline submenu.

When the functions are applied to polygon objects, the effect is indirect: the order of the points is changed for the selected polygons. This in turn changes the polygon coordinate system. Tools that use the polygon coordinate system such as Matrix Extrude will then have a different effect when applied to the polygons — see the example below.

The Move Up Sequence function applied to two selected polygons (left) and the result of applying Matrix Extrude to all of the polygons (right).
