Use these options to set what happens when you select Create > CV Curve Tool.
- Curve Degree
-
The higher the Curve Degree, the smoother the curve. The default setting (3 Cubic) works well for most curves. You must create at least one more CV than the Curve Degree number. For example, you need at least six CVs to complete a degree 5 curve:
See Degree for more details.
- Knot Spacing
-
The type of knot spacing sets how Maya assigns U position values to edit point (knots). Chord length knot spacing distributes curvature better. If you use the curve to build a surface, the surface might display textures better.
Uniform knot spacing creates curve U position values that are easier for you to predict. See Parameterization of NURBS curves and surfaces for details.
- Multiple End Knots
-
When turned on, the curve’s end edit points (knots) are superimposed on the end CVs. Generally, this makes the curve’s end region easier to control.
If you create a pair of curves with Multiple End Knots off, you can use Snap to Points to align the second CVs (next to the end CVs) of each curve to create tangent continuity between the two curves.
As with all tools in Maya, you can change the options after you create an object. Select the curve and open the Channel Box or the Attribute Editor.
