chordHeight, chordHeightRatio, delta, edgeSwap, format, fractionalTolerance, matchNormalDir, minEdgeLength, normalizeTrimmedUVRange, outputPolygon, polygonCount, polygonType, pre70ChordHeightRatio, uNumber, uType, useChordHeight, useChordHeightRatio, vNumber, vType

Long name (short name)	Type	Default	Flags
chordHeight (cht)	distance (double)	0.1cm
Chord height is the absolute distance in OBJECT space which the center of a polygon edge can deviate from the actual center of the surface span. Only used if Format is General and if useChordHeight is true.
chordHeightRatio (chr)	double	0.983
Chord height ratio is the ratio of the chord length of a surface span to the chord height. (This is a length to height ratio). 0 is a very loose fit. 1 is a very tight fit. (See also description of chord height.) Always used if Format is Standard Fit. Otherwise, only used if Format is General and useChordHeightRatio is true.
delta (d)	distance (double)	0.1cm
3D delta. Only used if Format is Standard Fit.
edgeSwap (es)	bool	false
Edge swap. This attribute enables an algorithm which determines the optimal method with which to tessellate a quadrilateral into triangles. Only used if Format is General.
format (f)	enum	1
Format: 0 - Triangle Count, 1 - Standard Fit, 2 - General, 3 - CVs
fractionalTolerance (ft)	double	0.01
Fractional tolerance. Only used if Format is Standard Fit.
uNumber (un)	integer	3
Initial number of isoparms in U. Used in conjunction with the uType attribute. Only used if Format is General.
vNumber (vn)	integer	3
Initial number of isoparms in V. Used in conjunction with the vType attribute. Only used if Format is General.
uType (ut)	enum	3
Initial U type tessellation criteria (3 types). Type 0 - Per surface # of isoparms in 3D. This type places a specific number of iso-parametric subdivision lines across the surface, equally spaced in 3D space. Type 1 - Per surface # of isoparms. This type places a specific number of iso-parametric subdivision lines across the surface, equally spaced in parameter space. Type 2 - Per span # of isoparms. This type places a specific number of iso-parametric subdivision lines across each surface span, equally spaced in parameter space. (This is the closest option to the Alias Studio tessellation parameters.) This attribute is only used if Format is General.
vType (vt)	enum	3
Initial V type tessellation criteria (3 types). See description for the uType attribute. Only used if Format is General.
matchNormalDir (mnd)	bool	false
Only used when the format is CVs. Order the cvs so that the normal matches the direction of the original surface if set to true.
minEdgeLength (mel)	distance (double)	0.001cm
Minimal edge length. Only used if Format is Standard Fit.
normalizeTrimmedUVRange (ntr)	bool	true
This attribute is only applicable when a trimmed NURBS surface is used as the input surface. When true, the UV texture coordinates on the trimmed input surface are normalized and applied to the output surface as they are for the untrimmed version of the input surface. (The texture coordinates on the entire untrimmed surface are mapped to the entire output surface.) When false, the UV texture coordinates on the trimmed input surface are applied to the output surface as they are for the trimmed input surface. (Only the texture coordinates visible on the trimmed input surface are mapped to the output surface.)
outputPolygon (op)	mesh	NULL
Output polygon
polygonCount (pc)	integer	200
The number of polygons to produce. Only used if Format is Triangle Count.
polygonType (pt)	enum	0
Polygon type: 0 - Triangles, 1 - Quads
pre70ChordHeightRatio (pchr)	bool	false
ChordHeightRatio evaluation changed in maya7.0 to match the behavior of this attribute on the nurbs surface shape node. Enabling this attribute will revert to the older behavior. The new behavior corresponds to roughly 1.0 minus the old value, although this simple math does not yield an exact match.
useChordHeight (uch)	bool	false
True means use chord height. Only used if Format is General.
useChordHeightRatio (ucr)	bool	true
True means use chord height ratio.
