A variety of ways to align the ground (or active item), with the position TransPSR can have a greater role

Alignment principle

non mesh object alignment: its origin

mesh object alignment: the highest or lowest point in the world Z axis

Alignment 1: all (lowest) > World floor

Most of the time, the method will be used to maintain the integrity of the selected objects’ structure

When selecting a single object, the alignment point of the single object is taken as the lowest point

When selecting multiple objects, the lowest alignment point of multiple objects will be taken as the lowest point (mesh object first)

Alignment 2: all > World floor

Hold down Ctrl and click the D2F button

Alignment 3: all > active

Hold down shift and click the D2f button

Alignment settings: all (excluding non MESH)

If checked, it has no effect on the movement of non-mesh objects, but it can still be used as the alignment target

It can be used in combination with the above three ways
