Cage creation script

Trying to make my cage creation faster and easier for Xnormal from 3ds max.

1.It must clone the object -working-
2.Change the name, add _Cage -working-
3.Add push modifier, controlled by spinner -working-
4.add edit normal modifier, select all normal and unify -in progress-
5.add reset xForm -to do-
6.Collapse all -to do-

So I have no idea how to select all face once my edit_normal modifier has been apply. If anyone has idea. I just need a little push :P .

here is what i have thus far

rollout MainMenu01 "Cage Creator" width:300 height:300
(
--start
group "Lowpoly"
(
pickButton PickedObject "Pick Lowpoly" pos:[75,25] width:150
label theObject "-- none --"
)

group "setting"
(
spinner CageScale "Cage Scale" type: #float range: [0, 1000, 0] width:75

button CreateCage "Create Cage" enabled:false
)

local thePickedObject

on pickedObject picked objectPickedByUser do
(
theObject.text = objectPickedByUser.name
thePickedObject = objectPickedByUser
CreateCage.enabled = true
)

on CreateCage pressed do
(
obj = thePickedObject
new_obj = copy obj
new_obj.name = obj.name +"_Cage"

select new_obj
max modify mode
addmodifier new_obj (Push ())
new_obj.Push.Push_Value = CageScale.value
max select none

select new_obj
max modify mode
addmodifier new_obj (Edit_Normals ())

)

)

createDialog MainMenu01
