Shrink Selection

收缩选择

This command shrinks the selection by deselecting all points, edges or polygons (depending on which mode you are in) at the edge of the selection.

这个命令通过取消选择选区边缘的所有点、边或多边形(取决于您所处的模式)来缩小选区。

If the polygon is closed (for example, a sphere) and you select all polygons, you cannot shrink the selection since it has no edge.

如果多边形是封闭的(例如，一个球体) ，并且您选择所有的多边形，您不能缩小选择，因为它没有边。

This function can also be used on selected UV points and polygons.

这个功能也可以用在选定的 UV 点和多边形上。
