Synopsis

geometryConstraint( [target ...] object , [name=string], [remove=boolean], [targetList=boolean], [weight=float], [weightAliasList=boolean])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

geometryConstraint is undoable, queryable, and editable.

Constrain an object's position based on the shape of the target surface(s) at the closest point(s) to the object. A geometryConstraint takes as input one or more surface shapes (the targets) and a DAG transform node (the object). The geometryConstraint position constrained object such object lies on the surface of the target with the greatest weight value. If two targets have the same weight value then the one with the lowest index is chosen.

Flags

name, remove, targetList, weight, weightAliasList
Long name (short name) [argument types] Properties
name(n) string createqueryedit
Sets the name of the constraint node to the specified name. Default name is constrainedObjectName_constraintType

In query mode, this flag needs a value.
weight(w) float createqueryedit
Sets the weight value for the specified target(s). If not given at creation time, the default value of 1.0 is used.

In query mode, this flag needs a value.
remove(rm) boolean edit
removes the listed target(s) from the constraint.
targetList(tl) boolean query
Return the list of target objects.

In query mode, this flag needs a value.
weightAliasList(wal) boolean query
Returns the names of the attributes that control the weight of the target objects. Aliases are returned in the same order as the targets are returned by the targetList flag

In query mode, this flag needs a value.
Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.

Return value


[string [] ] ( name of the created constraint node)

Python examples

import maya.cmds as cmds

# Constrain cube1 to surf1 at the closest point to  cube1.
cmds.geometryConstraint( 'surf1', 'cube1' )

# Will prefer surf1 though the weights are equal
cmds.geometryConstraint( 'surf1', 'surf2', 'cube2', w=.1 )

# Now constraints cube2 to lie on surf2 as it's weight is greater
cmds.geometryConstraint( 'surf2', 'cube2', e=True, w=10. )

# Removes surf2 from cube2's geometryConstraint.
cmds.geometryConstraint( 'surf2', 'cube2', e=True, rm=True )

# Adds surf3 to cube2's geometryConstraint with the default weight.
cmds.geometryConstraint( 'surf3', 'cube2' )
