rollout xrefmng “XREF”
(
edittext txtName “NAME” text:“NewName” width:130 height:18
button obj2xr “OBJ to XREF”
on obj2xr pressed do
(
disableSceneRedraw()
newpath = maxFilePath + “xref/”
makedir newpath
filepath = (newpath + txtName.text+”.max”)
if $ != undefined do
(
saveNodes $ filepath
delete $
)

objNames = getMAXFileObjectNames filepath
xrefs.addNewXRefObject filepath objNames dupMtlNameAction:#useScene
enableSceneRedraw()
)
)
