Add CAD capabilities to your .NET application with CadLib. CadLib makes it extremely easy to interface with, draw and print DWG and DXF files in C#, VB.NET or any other .NET language. This is achieved by providing the developer with a powerful, highly normalized class model, complete type safety, comprehensive documentation and sample solutions. CadLib can display DWG and DXF files in WPF, export to XAML, display using GDI+ (Windows Forms), and OpenGL. Furthermore CadLib provides converters to convert DWG and DXF files to all popular image formats as well as Pdf, PostScript and SVG. CadLib can be integrated in ASP.NET web applications.
