Parameters

WantCubic

True for surface to be a cubic, false for not

WantNonRational

True if non-rational is needed, false if not; specifying true converts any surface type to a non-rational Bsurface; if you specify true, then you should only use this method for surfaces that are Bsurface or blend surface; otherwise, the underlying call is not made and the values returned from this are not initialized or contain the values from the last call

Range

Array of 4 doubles describing the U,V Range

Tolerance

Tolerance, in meters, between the approximated b-spline surface and the underlying surface; the default value is 0.01 and should generally be reduced to the tolerance desired

Sense

Approximated b-spline surface is not always in the same direction as the original surface; if sense is true, then the underlying surface and the b-spline surface are in the same direction

Return Value

Size of the data set

Range contains the following values that can be obtained using ISurface::Parameterization or ISurface::IParameterization:

• Range[0] & Range[2] are the lower bounds of the U & V surface parameters respectively.

• Range[1] & Range[3] are the upper bounds of the U & V surface parameters respectively.
