public abstract class Entity104_ConicArc
extends GeomSSEntity

CONIC ARC ENTITY - This entity defines an ellipse, a parabola, a hyperbola, or a portion of one of these conic curves which may be isolated or used as a component of a Composite Curve or a sub-figure. The definition space coordinate system is always chosen so that the conic arc lies in a plane either coincident with or parallel to XT, YT plane. Within such a plane a conic is defined by the six coefficients in the following equation: A*XT^2 + B*XT*YT + C*YT^2 + D*XT + E*YT + F = 0

These entities (forms 0-3), when read from an IGES file, are converted to NURBS curves of degree 2 (IGES type 126, Form 2, Degree 2). This entity type can not be written out to an IGES file. All conic arc parameters are stored in the user data with the prefix "IGES_106_" followed by the parameter name.
