The paper introduced present research status of cubic parametric spline curve and software interfaces of AutoCAD,and put forward a data-exchange between figures containing cubic spline curve drew by AutoCAD and VC++ via DXF file format,and then abstracted target information,which was tangential values of start point and end point,number of fitting points and values of corresponding fitting points in the DXF file by VC++ program,and achieved parametric generation of cubic spline curve vie applying generation principle of cubic parametric spline curve presented.
