Object to curve constraint


This relation constrains an object to a curve. This can be useful to guide objects through 3D space without banging into other objects. The distance tolerance allows latitude to make the constraint less obvious.


Tangency aligns the object with the curve.


To constrain an object to a curve:
  1. Multi-select the object and then the curve that will serve as the path, in that order.
  2. Choose Relations > Object to Curve.
  3. When you translate the object, it moves along the path.

Object to Curve Parameters

Active

Toggles the constraint on and off.

Weight

Determines the weight of this constraint in relation to others constraints on the same object.

Position
parameter

Determines the object's location along the curve in percentage (from 0 to 100).

Distance
tolerance

Tolerance value in units by which the object can wander off the curve.

Enable tangency

Aligns the object with the curve.

Constrained
tangency

Determines which axis of the object is tangent to the curve. By default (1, 0, 0) the X axis lines up with the curve.
