Initializing Edit Curve Types


New Edit Curves may be initialized from the Curve tab where users may choose among a circle, ellipse, or rectangle. In practice, these are ways to initialize the three different curve types as Cubic Bezier, PCHIP Spline, or Linear, respectively. In each case, the new curve will be of unit coordinate height and width, ranging from -0.5 to 0.5 in both the horizontal and vertical axes. Note that initializing a new curve type does NOT alter the defined Scale XSec parameters controlling the height and width but rather creates a new curve in the coordinate space.
