Synopsis

scaleConstraint [-layer string] [-maintainOffset] [-name string] [-offset float float float] [-remove] [-scaleCompensate boolean] [-skip string] [-targetList] [-weight float] [-weightAliasList] [target...] [object]

scaleConstraint is undoable, queryable, and editable.

Constrain an object's scale to the scale of the target object or to the average scale of a number of targets.

A scaleConstraint takes as input one or more "target" DAG transform nodes to which to scale the single "constraint object" DAG transform node. The scaleConstraint scales the constrained object at the weighted geometric mean of the world space target scale factors.

Return value

string[]Name of the created constraint node

In query mode, return type is based on queried flag.

Flags

layer, maintainOffset, name, offset, remove, scaleCompensate, skip, targetList, weight, weightAliasList
Long name (short name) Argument types Properties
-layer(-l) string createedit
Specify the name of the animation layer where the constraint should be added.
-maintainOffset(-mo) create
The offset necessary to preserve the constrained object's initial scale will be calculated and used as the offset.
-name(-n) string createqueryedit
Sets the name of the constraint node to the specified name. Default name is constrainedObjectName_constraintType
-offset(-o) float float float createqueryedit
Sets or queries the value of the offset. Default is 1,1,1.
-remove(-rm) edit
removes the listed target(s) from the constraint.
-scaleCompensate(-sc) boolean createedit
Used only when constraining a joint. It specify if a scaleCompensate will be applied on constrained joint. If true it will connect Tjoint.aCompensateForParentScale to scaleContraint.aConstraintScaleCompensate.
-skip(-sk) string createeditmultiuse
Specify the axis to be skipped. Valid values are "x", "y", "z" and "none". During creation, "none" is the default. This flag is multi-use.
-targetList(-tl) query
Return the list of target objects.
-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.
-weightAliasList(-wal) 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
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 be used more than once in a command.

MEL examples

// Scale cube1 at the scale of cone1.
scaleConstraint  cone1 cube1;

// Uses the average of the scale of cone1 and surf2.
scaleConstraint -w .1 cone1 surf2 cube2;

// Sets the weight for cone1's effect on cube2 to 10.
scaleConstraint -e -w 10. cone1 cube2;

// Removes surf2 from cube2's scaleConstraint
scaleConstraint -e -rm surf2 cube2;

// Adds surf3 to cube2's scaleConstraint with the default weight
scaleConstraint surf3 cube2;

// Constrain the x and z scale of sph2 to sph1
scaleConstraint -skip y sph1 sph2;
