Hyperbolic Arc
Create a hyperbolic arc to be used either as a building block for constructing geometry or as a wire.
Hyperbolic arcs are often used in conjunction with the spin operator to create hyperbolic dishes for reflector antennas.
On the Construct tab, in the Create Arc group, click the Hyperbolic Arc icon.Tip: Press A,3 to use the shortcut key.
Method 1: Base centre, depth, radius, eccentricity

Base centre (C)  The centre of the hyperbola on which the arc lies. 
Depth (D)  The distance from the apex of the hyperbola to the centre of the arc aperture.  
Radius (R)  The radius of the aperture of the hyperbolic arc.  
Eccentricity  The eccentricity of the hyperbola on which the hyperbolic arc section lies. 
Method 2: Aperture centre, depth, radius, eccentricity

Aperture centre (C)  The centre of the aperture formed by the hyperbolic arc. 
Depth (D)  The distance from the apex of the hyperbola to the centre of the arc aperture.  
Radius (R)  The radius of the aperture of the hyperbolic arc.  
Eccentricity  The eccentricity of the hyperbola on which the hyperbolic arc section lies.
The eccentricity must be greater than one to specify a valid hyperbola. Note: Not
all values greater than one specifies a valid hyperbola.
