Drop Vertices

To Nearest Object（To Nearest Object） Animation Tutorial
The vertices of all edges on the surface are placed on the objects below them; If there are no objects below, place them on the objects above them; If there are no objects above or below, place them on the ground plane z = 0.

To Nearest Below（To Nearest Below） Animation Tutorial
The vertices of all edges on the surface are placed on the next object below them, or on the ground plane z = 0 if there are no objects below them.

To Nearest Above（To Nearest Above） Animation Tutorial
The vertices of all edges on the surface are placed on the next object below them, or on the ground plane z = 0 if there are no objects below them.

To Nearest+Z=?（To Nearest+Z=?） Animation Tutorial
Enter the default placement height Z value in the dialog box, and then it performs the operation equivalent to "to nearest object", but stops at the specified height (instead of Z = 0).

To Lowest（To Lowest） Animation Tutorial
The vertices of all edges on the surface are "dropped" to match the height Z value of the lowest selected vertex.

To Highest（To Highest） Animation Tutorial
The vertices of all edges on the surface are "raised" to match the height Z value of the lowest selected vertex.

To Middle（To Middle） Animation Tutorial
The vertices of all edges on the surface are "adjusted" to match the Z value of the middle height between the highest and lowest selected vertices.

To Average（To Average） Animation Tutorial
The vertices of all edges on the surface are "adjusted" to match the average height Z value of all selected vertices; It doesn't have to be the same as "to middle height." the disproportionately low number of vertices in the selection reduces the average, but it doesn't affect the middle value.

To Z=?（To Z=?） Animation Tutorial
Enter the height Z value in the dialog box, which is the current unit of the template by default; To use other units, add the unit directly after the value, such as "123mm". All the vertices of all edges on the surface will be placed with the specified height Z value. The default is Z = 0.

To Z=%（To Z=%） Animation Tutorial
Enter% [percentage] in the dialog box to place the selected vertex as a percentage of the height of the upper and lower objects. The default value is 100, which means "no change"; Enter 0 to flatten the surface.
