Scripting and dxf

Hi to All!!!
                Is LibreCAD able to import a Spline from a file of points? I would like to port an application from VB6 to Linux/Gambas that calculates the line of Cm velocity in a centrifugal pump or in a centripetal turbine and draw the lines in a CAD. It is possible to have a scripting interface in LibreCAD?
     Many thanks.
