Edit Poly Modifier Quick Detach

Hey guys I am trying to create a script that will allow me to detach subobject elements without being asked(options dialog box).

If I understand correctly you can't access the Edit Poly Modifier Detach options? (Detach as element, Detach as clone, ect.)

So I have been playing with some work arounds... Problem is! They both create extremely unstable geometry. They detach fine... but when I go to the newly created object and try to, for example, move the faces or chamfer a vertex... max crashes. On my work computer and home computer.

Any ideas to a better solution or to stabilize what I have?
Any help would be greatly appreciated. Been at this a few nights now.. :(

Work Around #1
- this one adds a second editpoly modifier... detaches with default settings then deletes the second editpoly modifier back off.

OriginalSOL = subobjectlevel
modPanel.addModToSelection (Edit_Poly ()) ui:on
$.modifiers[#Edit_Poly].name = "DetachEditPoly"
 
subobjectLevel = 4
$.modifiers[#Edit_Poly].DetachToObject "Junk"
 
 
DetachModIndex = modPanel.getModifierIndex $ $.modifiers[#DetachEditPoly]
deleteModifier $ DetachModIndex
 
 
EditpolyIndex = ((modPanel.getModifierIndex $ (modPanel.getCurrentObject())) + 1)
modPanel.setCurrentObject $.modifiers[EditpolyIndex]
subobjectlevel = 0
 
select $Junk
subobjectlevel = 4
$.EditablePoly.SetSelection #Face #{}

Work Around #2
- this one duplicates the mesh, takes the new one, jumps into face subobject level, inverts the selection, deletes it. Goes back to the original object, deletes originally selected faces.

OriginalDetachObj = $
OriginalModIndex = (modPanel.getModifierIndex $ (modPanel.getCurrentObject()))
OriginalSOL = subobjectlevel
--
suspendediting()
maxOps.cloneNodes $ cloneType:#copy newNodes:&nnl
select nnl
resumeediting()
 
modPanel.setCurrentObject $.modifiers[OriginalModIndex]
subobjectlevel = OriginalSOL
max select invert
$.modifiers[#Edit_Poly].ButtonOp #DeleteFace
max select all
subobjectlevel = 0
 
while(modPanel.getModifierIndex $ (modPanel.getCurrentObject())) != 1 do
(
	deleteModifier $ 1
)
macros.run "Modifier Stack" "Convert_to_Poly"
 
 
select OriginalDetachObj
modPanel.setCurrentObject $.modifiers[OriginalModIndex]
subobjectlevel = OriginalSOL
$.modifiers[#Edit_Poly].ButtonOp #DeleteFace

Detach elements from Editable Poly

This works for me in 3ds max 2017.
It detaches all elements from and editable poly object. Hope it is this what you wanted.

function fn_detachElements nin_Object = 
( 
 naOut = #()
 if classof nin_Object == Editable_Poly do
 ( 
   suspendediting()
   try
   (
    undo off
    (
     with redraw off
     (
     while polyOp.getNumFaces nin_Object != 0 do 
     (
      elementSel  = (polyOp.getElementsUsingFace nin_Object #{1})
      baseName  = nin_Object.name
      newName   = (uniqueName baseName)
 
      polyOp.detachFaces nin_Object elementSel asNode:true name:newName
      detachedObj = (getNodeByName newName)
      append naOut detachedObj
     )
 
     for o in naOut do
     (
      baseName  = (substring o.name 1 (o.name.count-3))
      uniquePart  = (substring o.name (o.name.count-2) o.name.count)
      finalName   = (baseName + "_" + uniquePart)
      o.name    = finalName
      centerPivot o
     )
    )
   )
  )
  catch(messageBox "error: detach objects")
  resumeediting()
 
  delete nin_Object
 )
 naOut as array
)
 
ep = teapot()
convertToPoly ep
fn_detachElements ep

Hi

Are you just try :

subobjectLevel = 4 	
$.EditablePoly.SetSelection #Face #{......}
polyop.detachfaces $ #{.....} asNode:true name:"YourString" -- detach as node 

Don't add modifier , no need .

Working?

did you ever get this to work? or figure out access to the detach as clone checkbox?
