# How do I Select a Face of an Editable Mesh by its Index?

MAXScript FAQ > Working With Editable Meshes > How Do I Select a Face of an Editable Mesh by its Index?

## A user asked:

Is there a way to select a face in an editable mesh when you only know its index?

## Answer:

When doing it just once, you can quickly type in the Listener something like

    setFaceSelection $ {10}

This will select face with index 10 assuming that a single object is selected and it is an Editable_Mesh.

If you are doing this very often, the following macroScript provides a UI with a spinner to select the face index and some error handling:

SCRIPT
    macroScript FaceByIndex category:"MXS Help"
    (
    global SelectFaceRoll
    try (destroyDialog SelectFaceRoll) catch()

    rollout SelectFaceRoll "Select Face"
    (
      spinner face_index "Face Index" type:#integer range:[1,100000000,1]
      onface_index changed valdo
      (
        if isValidNode selection[1] and classof selection[1].baseobject == Editable_Mesh do
        (
          if val <= selection[1].numfaces then
            setFaceSelection selection[1] #{val}
          else
            setFaceSelection selection[1] #{}
        )
      )
    )
    max modify mode
    try (subObjectLevel = 3) catch()
    createDialog SelectFaceRoll 150 30
    )--end macro
