Today I wrote a little tool that simply groups whatever you have selected, for the purposes of cleaning up transforms. Also works with multiple objects selected and groups them all under a group in the same worldspace as the first selected object.
Grab the code here and place it on your shelf.
import maya.cmds as cmds
import maya.OpenMaya as om
grpList = cmds.ls(sl = True)
parentObj = cmds.listRelatives( grpList[0], parent = True )
cmds.group( em = True, name = grpList[0] + '_Zero_GRP' )
cmds.parentConstraint( grpList[0], grpList[0] + '_Zero_GRP' )
cmds.delete( grpList[0] + '_Zero_GRP_parentConstraint1' )
cmds.scaleConstraint( grpList[0], grpList[0] + '_Zero_GRP' )
cmds.delete( grpList[0] + '_Zero_GRP_scaleConstraint1' )
cmds.parent( grpList[0], grpList[0] + '_Zero_GRP' )
try:
cmds.parent( grpList[0] + '_Zero_GRP', parentObj )
om.MGlobal.displayInfo( grpList[0] + ' now has a group above it' )
except:
om.MGlobal.displayInfo( grpList[0] + ' has no parent object, grouped in world space' )
cmds.select( grpList[0] )
newParent = cmds.listRelatives( parent = True )
listEndNumber = len(grpList)
remainingObj = grpList[1:int(listEndNumber)]
for i in remainingObj:
cmds.parent( i, newParent )
om.MGlobal.displayInfo( grpList[0] + ' now has a group above it' )
