pymel.core.animation.cutKey

static animation.cutKey(*args, **kwargs)

This command operates on a keyset. A keyset is defined as a group of keys within a specified time range on one or more animation curves. The animation curves comprising a keyset depend on the value of the -animationflag: keysOrObjects: Any active keys, when no target objects or -attribute flags appear on the command line, orAll animation curves connected to all keyframable attributes of objects specified as the command line’s targetList, when there are no active keys.keys: Only act on active keys or tangents. If there are no active keys or tangents, don’t do anything. objects: Only act on specified objects. If there are no objects specified, don’t do anything. Note that the -animationflag can be used to override the curves uniquely identified by the multi-use -attributeflag, which takes an argument of the form attributeName, such as translateX. Keys on animation curves are identified by either their time values or their indices. Times and indices can be given individually or as part of a list or range. -time 10palmeans the key at frame 10 (PAL format).-time 1.0sec -time 15ntsc -time 20means the keys at time 1.0 second, frame 15 (in NTSC format), and time 20 (in the currently defined global time unit).-time 10:20means all keys in the range from 10 to 20, inclusive, in the current time unit.Omitting one end of a range means go to infinity, as in the following examples: -time 10:means all keys from time 10 (in the current time unit) onwards.-time :10means all keys up to (and including) time 10 (in the current time unit).-time :is a short form to specify all keys.-index 0means the first key of each animation curve. (Indices are 0-based.)-index 2 -index 5 -index 7means the 3rd, 6th, and 8th keys.-index 1:5means the 2nd, 3rd, 4th, 5th, and 6th keys of each animation curve.The cutKey command cuts curve segment hierarchies from specified targets and puts them in the clipboard. The pasteKey command applies these curves to other objects.The shape of the cut curve placed in the clipboard, and the effect of the cutKey command on the source animation curve depends on the cutKey -optionspecified. Each of these options below will be explained using an example. For all the explanations, let us assume that the source animation curve (from which keys will be cut) has 5 keyframes at times 10, 15, 20, 25, and 30.TbaseKeySetCmd.h cutKey -t 12:22-option keysKeyframes at times 15 and 20 are removed.

Shift all keys after time 20 to the left by 5 frames, and place the key that used to be at time 25 at the value of the key that used to be at time 15.A 5-frame animation curve is placed into the keyset clipboard.cutKey -t 12:22-option curveKeyframes at times 15 and 20 are removed. Keys are inserted at times 12 and 22.A 10-frame animation curve is placed into the keyset clipboard.cutKey -t 12:22-option curveCollapseKeyframes at times 15 and 20 are removed. Keys are inserted at times 12 and 22. Shift all keys from time 22 to the left by 10 frames, preserving their values.A 10-frame animation curve is placed into the keyset clipboard.cutKey -t 12:22-option curveConnectKeyframes at times 15 and 20 are removed. Keys are inserted at times 12 and 22. Shift all keys from time 22 to the left by 10 frames, and replace the key inserted at time 12 with the newly inserted key at time 22.A 10-frame animation curve is placed into the keyset clipboard.cutKey -t 12:22-option areaCollapseKeyframes at times 15 and 20 are removed. Shift all keys from time 22 to the left by 10 frames, preserving their values.A 10-frame animation curve is placed into the keyset clipboard.

Flags:

Long name (short name)		Argument Types	Properties
animation (an)		unicode
	Where this command should get the animation to act on. Valid values are objects,keys,and keysOrObjectsDefault: keysOrObjects.(See Description for details.)
attribute (at)		unicode
	List of attributes to select
clear (cl)		bool
	Just remove the keyframes (i.e. do not overwrite the clipboard)
controlPoints (cp)		bool
	This flag explicitly specifies whether or not to include the control points of a shape (see -sflag) in the list of attributes. Default: false. (Not valid for pasteKeycmd.)
float (f)		floatrange
	value uniquely representing a non-time-based key (or key range) on a time-based animCurve. Valid floatRange include single values (-f 10) or a string with a lower and upper bound, separated by a colon (-f 10:20
hierarchy (hi)		unicode
	Hierarchy expansion options. Valid values are above,below,both,and none.(Not valid for pasteKeycmd.)
includeUpperBound (iub)		bool
	When the -t/time or -f/float flags represent a range of keys, this flag determines whether the keys at the upper bound of the range are included in the keyset. Default value: true. This flag is only valid when the argument to the -t/time flag is a time range with a lower and upper bound. (When used with the pasteKeycommand, this flag refers only to the time range of the target curve that is replaced, when using options such as replace,fitReplace,or scaleReplace.This flag has no effect on the curve pasted from the clipboard.)
index (index)		int
	index of a key on an animCurve
option (o)		unicode
	Option for how to perform the cutKey operation. Valid values for this flag are keys, curve, curveCollapse, curveConnect, areaCollapse. The default cut option is: keys
selectKey (sl)		bool
	Select the keyframes of curves which have had keys removed Flag can have multiple arguments, passed either as a tuple or a list.
shape (s)		bool
	Consider attributes of shapes below transforms as well, except controlPoints. Default: true. (Not valid for pasteKeycmd.)
time (t)		timerange
	time uniquely representing a key (or key range) on a time-based animCurve. Valid timeRanges include single values (-t 10) or a string with a lower and upper bound, separated by a colon (-t 10:20

Derived from mel command maya.cmds.cutKey

Example:

import pymel.core as pm

# Cut keyframes from frame 10 to 20 of cube1's "Translate X" attribute
#
pm.cutKey( 'cube1', time=(10,20), attribute='translateX', option="keys" )

# Cut from all active objects all keys in the range 0 to 60
#
pm.cutKey( time=(0,60) )
