This tool creates the polar or diameter line of a conic section (see also Polar command).
  • Select a point and a conic section to get the polar line of the given point (relative to the given conic).
  • Select a line or a vector and a conic section to get the conjugate diameter of the diameter parallel to the given line or vector (relative to the given conic).
