SurfaceSelect

Selects subobject-elements based on the curvature of the surface. If the Concave option is choosen it will select areas that are pushed in, like cavities. If the convex option is active it will select areas that are outward pointing, like the surface of a sphere. Drag the spinner to make and adjust the selection. The value in the spinner determines how much convex or concave the surface needs to be in order to be selected.

Tip: If you have your UVW map laid out in a good way you can use the SelectionToBitmap feature to export the selection to a bitmap.

NormalSelectSelects subobject-elements based on the normal direction of the elements. "X","Y" and "Z" determines which direction(axis) the elements to be selected should point. By dragging the "Angle" spinner you can interactively control how much the subobject-elements can point away from the specified direction to in order to still get selected. As an example, setting the axis to "Z" and dragging the spinner in polygonmode will select all polygons that point up to a certain degree. The "Invert" checkbox inverts the desired direction and would in this case select all polygons that point down to a certain degree.

PerspectiveSelect

Selects subobject-elements based on how much they are pointing towards user in the active view. You can think of it as projecting as selection onto the model from the current view. The "Angle" spinner determines at which angle elements can point away from the view in order to still get selected. The higher the value, the more elements angled away from the view gets selected. If the "Outline" checkbox is checked the tool will automatically perform an outline action on the selection.

Tip: If Shift is pressed the tool will operate within the current selection only.

Shortcut: When assigned as a shortcut this tool will always use 30 as the degree angle, and when used in edge subobject mode the outline function will always be turned on.

SelectHalf

Selects half of the mesh on the specified axis. If the "Invert" checkbox is checked the opposite half will be selected. The middle of the mesh is determined by the location of the models pivot.

DistanceSelect

Selects subobject-elements based on how far they are from the models pivot. Interactively drag the spinner to select elements based on the percentage amount in the spinner. If the pivot is centered, a value of 100% means the whole object is unselected and any value below that will result in the outer parts of the model getting selected.

PerspectiveGrow

Selects and grows subobject-elements based on the current view and inwards into the view. The closest part of the model will be selected first and the higher the value in the spinner, the further into the view the selection will go.

Even/Odd

Even

Selects subobject-elements that have even numbers like 2,4,12 and so on. The "Skip" spinner determines how many numbers to skip between the even numbers, so a value of 1 will select elements numbered 2,4,6,8 and so on. A value of 2 will select elements numbered 2,6,10,14 and so on.

Shortcut: When used as a shortcut this tool will default to 1 as a skip value.

Odd

Selects subobject-elements that have odd numbers like 1,3,15 and so on. The "Skip" spinner determines how many numbers to skip between the odd numbers, so a value of 1 will select elements numbered 1,3,5,7 and so on. A value of 2 will select elements numbered 1,5,9,13 and so on.

Shortcut: When used as a shortcut this tool will default to 1 as a skip value.

Nth Sel

Selects the next even or odd numbered element in the model. Because of the way the numbers are laid out in a basic primitive in max, this will in a way duplicate the selection further down the element numbers. The "Step" spinner determines how big the jump is to the next selection. If the "Reverse(Rev)" checkbox is checked the selection will be created in the opposite way, and if the "Move" checkbox is checked the selection will not be duplicated, but moved instead.
