Put Pivot To Center modifier

Try the second button. Other wise I am at a total loss as to what your trying to do.

	try(destroydialog xFormAdjustRO )catch()
	rollout xFormAdjustRO "Adjust Pivot" width:160 height:102
	(
		----UI
		button ctoBtn "Center Object to Pivot" pos:[16,32] width:128 height:20 toolTip:"Have a XForm align its Gizmo so that the object can be centered to the pivot as if the \"Align to Pivot\" action with \"Affect Object Only\" was used"
		button ctpBtn "Center Pivot to Object" pos:[16,60] width:128 height:20 toolTip:"Have a XForm align its Gizmo so that the object can be centered to the pivot as if the \"Align to Pivot\" action with \"Affect Object Only\" was used"
		groupBox grp1 "Alignment:" pos:[8,8] width:144 height:86
		
		----FUNCTIONS
		fn affectXForm oORp=
		(
			curMod = modPanel.getCurrentObject()
			if (classof curMod == XForm) then
			(--do event
				local GizmoTrans , copyTrans
				undo off
				(
					disablesceneredraw()
					curObj = selection[1]
					copyObj = copy curObj
					modNum = finditem curObj.modifiers curmod
					maxOps.CollapseNode copyObj true
					CenterPivot copyObj
					difTrans = copyObj.transform * (inverse curOBJ.transform)
					copyTrans = copyObj.transform
					delete copyObj
					enablesceneredraw()				
				)
				undo "Center Xform" on
				(
					curMod.gizmo.transform = inverse difTrans
					if oORp then curObj.transform = copyTrans
				)
			)
			else 
			(--print message asking to select a xform modifiers in the mod panel
				MessageBox "No XForm Modifier is selected in the modifier panel. To edit the Xform please select the XForm modifier in the modifier panel and try again."   
			)
		)--end affectXForm fn
		
		----EVENTS
		on ctoBtn pressed do AffectXForm false
		on ctpBtn pressed do AffectXForm true	
			
	)--End xFormAdjustRO
	createDialog xFormAdjustRO

yeah, it center object to its pivot position, but i need opposite - put object's pivot to its center automatically (as modifier)

actually just one checkbox "center pivot" in existing XForm modifier will be enough

thank you anyway)

Give this a try. Select the Xform modifier in the mod panel and click the button. Not sure if this is what your where looking for.
