This is the overview for the contentCurve method overload. 
 
is3d 
Returns the current curve's 3D flag value. The flag is equal to true if the curve is a 3D object or is equal to false in the other case. 
 
Returns the current parameterization information used for the curve. 
 
read 
Reads curve data from a specified input stream, and creates and returns a curve entity.
 
 
Reads data from a specified input stream into a curve array.
 
 
Reads curve data from a specified input stream, creates a curve, and returns a smart pointer to an OdPrcCurve object.
 
 
Sets new parametrization information to the curve.
 
 
Writes data from a curve array to a specified output stream.
 
 
Writes curve data to a specified output stream.
