OdDbArc::getPointAtParam Method
Syntax
C++
virtual OdResult getPointAtParam(double param, OdGePoint3d& pointOnCurve) const;
Parameters 
Description 
double param 
[in] Parameter value specifying the point on the circular curve as a Double value in radians.  
OdGePoint3d& pointOnCurve 
[out] Reference to a variable in which this method must save the three-dimensional point instance corresponding to the parameter. 

Computes the WCS coordinates of the point on the circular arc at the specified parameter value. Parameter is an angle measured counterclockwise from the OCS X-axis in the range 0 to 2PI radians.
