When you select Edit Curves > Modify Curves > Lock Length, the selected curve (or selected CVs) will maintain a constant hull length. If you then modify the curve, for example, by
moving a CV, the shape of the curve will adjust so that it maintains a constant hull length (that is, CVs other than the one
you move will also move).
When you select Edit Curves > Modify Curves > Lock Length, a attribute is added to the curveShape node.
Notes
- You can use the l (lower-case L) key as a momentary hotkey. Press and hold down the l key to lock the length of the selected
curve. Release the l key to unlock the length of the curve.
- is useful for modeling purposes. Because modifying a curve with turned on behaves similar to a dynamic simulation, animating a curve in this way (with keyframes) may produce unexpected
results.
- If you turn on , move a CV and then select , only the CV you moved will return to its original position.
- If you turn on and modify the curve, the curve’s first CV will not move (unless you explicitly move the first CV). For example, if you move
the curve’s first CV, the curve will respond differently than if you move the curve’s last CV.
