ModifyCurveShape Constraint

The Curve Shape Constraint command enables you to select a curve in an arbitrary location and modify its shape using a temporary handle. The handle can be positioned at any arbitrary location on the curve.

If the selected curve is not a NURBS, if the Ask before converting check box is selected, you will be asked to convert it into a NURBS. The conversion precision is controlled by the Tolerance parameter.

A set of Quality Checks is also available, enabling you to analyze the curvature of the selected curves.

Try to ...

• Move selected location without modifying tangency conditions
• Rotate tangent vector around selected location, while keeping its magnitude unchanged
• Modify tangent vector magnitude, while keeping its direction unchanged
• Modify both direction and magnitude of tangent vector
