The Conic command draws a conic section curve.
|1.||Pick the start.|
|2.||Pick the end.|
|3.|| Pick the apex.
This location partially defines the plane for the conic.
|4.|| Pick a location for the conic to pass through to define its curvature.
Or, type a the rho value (a number greater than 0 and less than 1), and press Enter.
Note: The status bar displays the rho value during the command.
Pick the apex ("top" control point).
Select a curve and then drag the tangent indicator to the desired location.
Select a curve and then drag the perpendicular indicator to the desired location.
Types of conics
The intersection of a right circular cone and a plane that passes through the side of the cone and the base of the cone.
Rho value of 0.5.
The intersection of a right circular cone and a plane perpendicular to the cone's base.
Rho values greater than 0.5 and less than 1.
Draw lines and curves
Draw a hyperbolic curve from focus points, vertices, or coefficient.
Draw a parabolic curve from focus and vertex or endpoint.
