12 | Basics Menus Reference > Create > CV Curve Tool Adjust cap subdivisions after create Adds additional steps to the Interactive Creation process that let you adjust the cap subdivisions on primitives that contain caps (Cylinder, cone, pyramid, prism, helix, pipe). The default setting is off. This option can only be used when the Adjust subdivisions after create option is turned on. Create > CV Curve Tool Lets you draw a NURBS curve by placing CVs. Related topics "Components of NURBS curves" on page 19 "Draw curves" on page 25 "Create > EP Curve Tool" on page 255 "Display > NURBS" on page 299 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: 6 1 234 5 See "Degree" on page 11 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" on page 12 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. Basics 254
