CAD Import .NET is a user-friendly API that can read AutoCAD DXF, DWG, and HPGL PLT files in Microsoft Visual Studio environments. It is completely programmed in C# and includes features such as viewer, editor, import, merge files, add entities, and viewer control for demo purposes.

CAD Import .NET supports a wide range of file formats including AutoCAD DWG, DXF, Hewlett-Packard: HPGL, HGL, HG, PRN, SPL, Windows metafile: EMF, WMF, all popular raster drawings like TIFF, BMP, JPG, and GIF, Computer Graphics Metafile: CGM, and the Gerber file format - GBR. Moreover, this library can process drawing segments by copying segments of drawings to the clipboard in raster (BMP) and vector (EMF) formats, printing segments of drawings and saving segments as separate files (DXF, PDF, BMP, etc).
With CAD Import .NET, you get drawings editing features that support both standard CAD formats such as DWG and DXF, as well as other vector files like PLT, HPGL, and CGM. This functionality extends to visual entities creation and editing using markers with Snap options, and access to entities' properties.
The library also comes with drawings converting and export features, enabling you to copy to the clipboard as BMP, EMF/WMF and export drawings to raster and vector formats. You can conveniently view drawings in full 2D/3D rotating mode, manage layers and objects properties, scale, zoom, and drag.
CAD Import .NET also has printing capabilities that generate pages, support fragmentary printing, and merging of documents while offering fast drawing mode. Other additional features that make CAD Import .NET stand out include support of UNICODE for hieroglyphs display, SHX fonts for DWG and DXF, and drawing of TTF-fonts as polylines. Plus, the flexibility of using it in ASP.NET, support of web-paths and loading from the web, make CAD Import .NET a software that's hard to match.
