Description Adds a classic aspheric surface to the associated FRED document.
Syntax n = AddAsphere( entity, curv, conic, evens, odds )
Parameters n (Long) Node number of the added surface.
entity As T_ENTITY The basic entity parameters of the surface.
curv As Double The curvature of the Aspheric surface. (cv = 1/radius).
conic As Double The conic constant of the Aspheric surface. 0=sphere, -1=parabola, <-1=hyperbola, etc.
evens() As Double Array of the even order coefficients of the Aspheric surface.
odds() As Double Array of the odd order coefficients of the Aspheric surface.
Remarks This function adds an Aspheric surface to the associated FRED document and returns the identifier for the added surface.
The sag equation of the surface is:
and
r = Sqrt( x2 + y2)
