Creates a conic given two points on the conic section, the starting and ending slopes, and the projective discriminant. The lines defined by the two points and their respective slopes are intersected to establish the anchor point.

To control the slope of the curve at the endpoints, use one of the following options:

Vector Components	Defines the slope of an imaginary line from the origin through a position you enter in work coordinates.
Direction Point	Lets you use a direction relative to the first point of the curve which lies along the slope.
Slope of Curve	Lets you define the slope by selecting a curve endpoint.
Angle	Lets you define the slope by entering an angle.

The projective discriminant, Rho, is used to determine a third point on the conic section. Consider a line constructed from the anchor point to the midpoint of the line connecting the two endpoints of the conic section. The third point on the conic section lies somewhere along this line.

The value entered for Rho must be between 0 and 1. The type of conic section created is determined by this value.

• If Rho is < 1/2, an ellipse is created.

• If Rho is = 1/2, a parabola is created.

• If Rho is > 1/2, a hyperbola is created.
