When creating tangent constraints, you can first set creation options and then create a tangent constraint, or you can immediately create a constraint with the current creation options.
Typically, you would want to first create a geometry constraint to constrain the object to some curve, and then create a tangent constraint to constrain the object’s orientation so that it aligns with the tangents of the curve.
The default constraint options work well for constraining objects so that they aim along their local rotation positive X-axis.
To create a tangent constraint
- Select one or more target objects, followed by the object you want to constrain to them.
- Select Constrain > Tangent >
to view the Tangent constraint options.
