Lock or unlock the length of a curve

You can lock the length of a curve so that it maintains a constant hull length, even when you edit the curve (for example, by moving a CV).

To lock/unlock the length of a curve

1. Select the curve (or CVs).
2. Press and hold down the l (lower case L) key.
3. Modify the curve, and it will maintain a constant hull length.
4. To unlock the length, release the l (lower case L) key.
   Note:

   You can also lock/unlock the length of a curve by selecting the curve (or CVs), and selecting Curves > Lock Length or Curves > Unlock Length, but be careful you don’t forget to unlock the length. Using the hotkey is better, because you’re not likely to forget to unlock the length.

   Note: When you first lock the length of a curve, a Lock Length attribute is added to the curveShape node. You can thereafter lock/unlock the length of the curve by turning on/off the Lock Length attribute.
