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.

NEW: Added support for rendering to WriteableBitmap which can be used in UWP (.NET Standard version of CadLib only)!
NEW: Added support for .NET Standard (can be used in .NET Core)!
NEW: Added support for AutoCAD 2018 DWG and DXF!

Read, write and display AutoCAD™ DWG and DXF files in C#, VB.NET or any other .NET language. Download the trial version and get up and running in minutes. CadLib provides complete type safety, comprehensive documentation and sample solutions. CadLib's rendering is high quality and easy to integrate in your own application. Display DWG and DXF files using GDI+, WPF or OpenGL. Conversion to XAML is also supported.

A high quality configurable PDF converter is included, that optionally creates searchable PDF files. An example console application is included (see the export example) that demonstrates the conversion from an AutoCAD DWG or DXF file to PDF.

Example solutions written in C# and VB.NET show how to add more advanced features like zooming, panning and picking. Samples are included that demonstrate use with Windows Forms, WPF, OpenGL and ASP.NET 4.0.

VS 2017: by default the help viewer is not installed. To install and use the CadLib help files, first install the VS help viewer, and Set 'Help Preference' to 'Launch in Help Viewer'. See here for an howto.

For the .NET Standard version of CadLib that can be used in .NET Core and Universal Windows, see here.
