Description Adds a conic foci surface (ellipsoid or hyperboloid) to the associated FRED document.
Syntax n = AddConicFoci ( entity, foci )
Parameters n (Long) Node number for the new Conic Foci surface.
entity As T_ENTITY The generic entity data for the new surface.
foci As T_CONICFOCI Structure containing the ellipsoid/hyperboloid data for the new Conic Foci surface.
Remarks This function adds a conic foci surface (either an ellipsoid or a hyperboloid) to the associated FRED document and returns the identifier for the new surface. The function returns a value of -1 if the surface could not be created or added to the document.
A Conic Foci surface is axially symmetric ellipsoid/hyperboloid specified by a point on the surface and the location of its two foci. Note that a sphere can be created by specifying the two foci to be coincident at the center of the sphere.
