pymel.core.general.group

group(*args, **kwargs)

This command groups the specified objects under a new group and returns the name of the new group. If the -em flag is specified, then an empty group (with no objects) is created. If the -w flag is specified then the new group is placed under the world, otherwise if -p is specified it is placed under the specified node. If neither -w or -p is specified the new group is placed under the lowest common group they have in common. (or the world if no such group exists) If an object is grouped with another object that has the same name then one of the objects will be renamed by this command.

Modifications

• if no objects are passed or selected, the empty flag is automatically set

Maya Bug Fix:

• corrected to return a unique name

Flags:

Long name (short name)		Argument Types	Properties
absolute (a)		bool
	preserve existing world object transformations (overall object transformation is preserved by modifying the objects local transformation) [default]
empty (em)		bool
	create an empty group (with no objects in it)
name (n)		unicode
	Assign given name to new group node.
parent (p)		unicode
	put the new group under the given parent
relative (r)		bool
	preserve existing local object transformations (relative to the new group node)
useAsGroup (uag)		unicode
	Use the specified node as the group node. The specified node must be derived from the transform node and must not have any existing parents or children.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
world (w)		bool
	put the new group under the world

Derived from mel command maya.cmds.group

Example:

import pymel.core as pm

import maya.cmds as cmds

# create an empty group node with no children
pm.group( em=True, name='null1' )
# Result: nt.Transform(u'null1') #

# create some objects and group them
pm.sphere( n='sphere1' )
# Result: [nt.Transform(u'sphere1'), nt.MakeNurbSphere(u'makeNurbSphere1')] #
pm.circle( n='circle1' )
# Result: [nt.Transform(u'circle1'), nt.MakeNurbCircle(u'makeNurbCircle1')] #
pm.group( 'circle1', 'sphere1', n='group1' )
# Result: nt.Transform(u'group1') #

# create a group node under another node and move
# the sphere under the new group node.
pm.group( 'sphere1', parent='null1' )
# Result: nt.Transform(u'group2') #
