This software library allows CAD integration into VC++, C#, Delphi and more, without needing to install AutoCAD. The royalty-free license has no time limitations and supports various formats including DWG/DXF, DWF, HPGL/HGL, PLT, CGM, SVG, TIFF, BMP and JPG.

One of the best things about CAD DLL is that you can seamlessly integrate it into your applications developed in VC++, C#, Delphi, ASP .NET, C++Builder, Visual Basic, and VB.NET. No need to rely on AutoCAD or any other third-party software. Plus, the license is royalty-free and has no time limitations, which means you can use it for as long as you want.
CAD DLL is available in 32- and 64-bit versions on Windows platform and can also be used on Linux. Technical information and free technical support are readily available to help you implement the library into your project quickly and easily.
The trial version of CAD DLL includes examples of applications in Visual C++; C#, Delphi, ASP .NET, and other programming languages demonstrating the use of import, viewing, and export drawings functions. The import feature also allows you to access entity properties such as coordinates, layers, blocks, attributes, etc.
With the export feature, you can save the drawing in a vector or raster format or convert it into vector formats like AutoCAD DWG/DXF (including DWG 2004), PDF, SVG, CGM, HPGL, EMF, WMF, or raster formats such as BMP, JPG, GIF, PNG, and more. Through the Windows Metafile technology, it's also possible to export to AutoCAD DWG/DXF and other CAD formats by writing just a short code script.
CAD DLL supports Unicode and SHX fonts, including big fonts and Asian symbols. You can also rotate a drawing by xy-coordinate axes, manage layers, select the background color and the drawing scale, as well as change the line color and weight.
