CadLib 3.5 for .NET is an efficient software that can be integrated with your .NET application to enable CAD functionalities. It allows easy communication, drawing and printing of DWG and DXF files using any .NET language such as C# and VB.NET.

One of the standout features of this library is the fact that it allows you to view DXF files using either 3D surface rendering with OpenGL or 3D wire frames drawn with GDI+/WPF. With entity selection for use with a mouse, the tool is also highly intuitive and easy to use.
In addition to the above functionality, this library also allows you to export files to a range of image formats, including .bmp, .jpeg, .png, .tiff, and .gif. Plus, you can export to PDF, PostScript, and SVG for added versatility.
Supporting both 2D and 3D, this tool can read compressed DXF files in zip, tar, bz2, and gz formats. It's also 100% .NET code, with all DXF objects exposed as .NET classes and typesafe collections. Convenient enums are provided for all flags in DXF for even greater ease of use.
With this library, you'll be able to take your .NET application to the next level by creating AutoCAD files that accurately reflect your design vision. And, you'll also be able to import, view, and print AutoCAD files for added convenience. All in all, this tool is a must-have for anyone working with AutoCAD files in a .NET context.
