Hi, is it possible to get CadLib to render OpenGL into an existing OpenGL application? I have an application that uses OpenTK and I want to get CadLib to render the Dxf drawing along side OpenGL drawings made by the existing program. Thanks, Euan

Yes, I don't see why it shouldn't work, as long as you make the rendering context current before making the OpenGL calls. I don't have the environment to try this out though. - Wout
