DXF Export .NET allows programmers to create DXF files as easy as possible. There are two ways of creating DXF: - Direct DXF export when all the elements created step-by-step by functions like AddLine/AddArc and so on and - AutoDXF export using GDI+ Metafile. All you need here is to draw image using Windows GDI+ functions onto DXF Exporter’s DC or make a metafile and give it to the Exporter. DXF Exporter reads GDI+ Metafile structure and makes DXF file automatically.
