Object^ Evaluate( 
&   double Param
) 

Parameters

Param

Curve parameter desired (U value desired for evaluation)

Return Value

Array of doubles (see Remarks)

The tangency vector is defined to be in the direction of the coedge.

The format of the return value is an array of 6 doubles:

• retval[0] x location on the curve 

• retval[1] y location on the curve 

• retval[2] z location on the curve 

• retval[3] x vector describing the tangency at the parameter location on the coedge 

• retval[4] y vector describing the tangency at the parameter location on the coedge 

• retval[5] z vector describing the tangency at the parameter location on the coedge
