| Position | Tangent | Up Vector Options

Constrains the center of an object among three other objects. By default, the object is constrained by its X axis, although constraint by any axis is possible.

For more information, see Constraining an Object within Three Points [ Animation ].

To apply: Select an object, Constrain 3 Points, then pick the three objects among which the selected object will be constrained.

To redisplay: Select the constrained object, choose Explore Constraints on the MCP, and click the constraint's icon.

Position

Active

Toggles the activeness of this constraint.

Blend Weight

Blends the weight of this constraint with other constraints on the selected object.

U/V/W %age (Percentage)

Uses U, V, and W coordinates to set the relative distance of the constrained object between its constraining objects. A value of 33.33 positions the constrained object centrally between the three constraining objects.

A U value of more than 33.33 positions the constrained object closer to the first constraining object; a V value of more than 33.33 positions the constrained object closer to the second constraining object; and a W value of more than 33.33 positions the constrained object closer to the third constraining object.

Attach Point -- Constrained Object

Affected by Orientation

Constrained object is affected by the orientation of the constraining object.

Affected by Scaling

Constrained object is affected by the scale of the constraining object.

X/Y/Z

Sets the offset distance in global space on the X/Y/Z axes of the constrained object in relation to the constraining objects. If you add an offset, you can set the Coupling to either soft or rigid.

Coupling

Coupling

Determines how constrained object move in relation to the constraining object when there is an offset between them (set with the X/Y/Z sliders). When the offsets for both the constrained and constraining objects are set to zero (off), the coupling has no effect.

Rigid: The constrained object mimics the rotation of the constraining object. Rigid constraints are represented by a small square in the center of the constraining object.

Soft: The constrained object is allowed a certain degree of flexibility in relation to the constraining object, similar in nature to a ball joint. Soft constraints are represented by a small circle in the centers of the constrained and constraining objects.

Tangent

Active

Toggles the activeness of the tangency values set for this constraint.

Axis to Align

X/Y/Z

Sets the axis of the constrained object that will always face the averaged positions of the constraining objects. You can either click the axis buttons (positive and negative X, Y, Z) or enter 1 or -1 in the axis text boxes.

Up Vector

The up-vector constraint makes the Y axis of a constrained object point to a constraining (control) object or a specific point. See Up Vector Options for information.
