Structure:

parameters: (optional) NX_NUMBER (Rank: 1, Dimensions: [10]) {units=NX_PER_LENGTH}

Ten real values of the matrix that defines the quadric surface in projective space. Ordered Q11, Q12, Q13, Q22, Q23, Q33, P1, P2, P3, R. Takes a units attribute of dimension reciprocal length. R is scalar. P has dimension reciprocal length, and the given units. Q has dimension reciprocal length squared, and units the square of those given.

surface_type: (optional) NX_CHAR
