# Started with maxscript : Polygon coordinate

Hi guys,
i try to learn maxscript and i'm actually freeze in my code since a fex days..

I would like to move an object (let say a Teapot) on a polygon from an other object.

So here, i start the script by selected some polygon and set the selection on an array.

Next i select one polygon from this array and .....

how can i get the coordinate of this poligon ?

so i'll be able to move the teapot like:

x=(coordsys world ???.pos.x)
y=(coordsys world ???.pos.y)
z= (coordsys world ???.pos.z)

move Teapot001 [x,y,z]

Here is my code:

rollout myscript "test width:280 height:141
(

GroupBox 'grp1' "Object on Element" pos:[10,10] width:255 height:112 align:#left
pickbutton 'itemdest' "-- none --" pos:[140,30] width:120 height:20 align:#left
label 'lbl1' "Main Object" pos:[20,30] width:100 height:15 align:#left
button 'btn1' "Move" pos:[140,95] width:120 height:20 align:#left

on itemdest picked obj do
(
itemdest.text = obj.name
dest = obj
)
on btn1 pressed do
(

select dest
max modify mode
subobjectlevel = 4

numFaces = polyOp.GetNumFaces dest
angleSelection = #{}
prov1 = #()

for f=1 to (numFaces) do
(
faceNorm = polyOp.getFaceNormal dest f
angle = acos faceNorm.z
if ((angle >= 0) and (angle <= 10)) then angleSelection[f] = true
)
polyOp.setFaceSelection dest angleSelection

SelectedFaces = getFaceSelection dest
if SelectedFaces.numberset != 0 do prov1 += SelectedFaces

temp=polyop.setfaceselection dest prov1[random 1 prov1.count]

)
)

Thx for helping !

1) select your dest object(which you will pick with the [-- none --] button), go to Polygon subobject level and select one polygon.
2) select the object you want to move
3) press the [ Move ] button

```(
rollout myscript "test" width:280 height:141
(
local destObj = undefined

GroupBox 'grp1' "Object on Element" pos:[10,10] width:255 height:112 align:#left
pickbutton 'itemdest' "-- none --" pos:[140,30] width:120 height:20 align:#left
label 'lbl1' "Main Object" pos:[20,30] width:100 height:15 align:#left
button 'btn1' "Move" pos:[140,95] width:120 height:20 align:#left

on itemdest picked obj do
(
itemdest.text = obj.name
destObj = obj
)
on btn1 pressed do
(
if selection.count == 1 do
(
selFaceIdx = ((polyop.getFaceSelection destObj) as array)[1]
sefFaceCenter = polyop.getFaceCenter destObj selFaceIdx
selFaceNormal = polyop.getFaceNormal destObj selFaceIdx

selection[1].pos = sefFaceCenter
selection[1].dir = selFaceNormal
)
)
)
createDialog myscript
)```
