Hi! I am trying to generate my custom parametric surfaces like NURBS, Bezier patches, for my research in Manufacturing. To start with I am trying to write a code in C++, for plotting a line, using NX OPEN application wizard of Visual Studio9 and then running the .dll file in NX. I am stuck on the point, about what libraries/functions to use so that when the code runs in NX, I can get the display of a line and two points on the NX Open Interface. I am sure, if I can get a line, I can extend it to get curves and subsequently surfaces.
