C# library to read/write cad files like dxf/dwg.


ACadSharp allows to read or create CAD files using .Net and also extract or modify existing content in the files, the main features may be listed as:

  • Read/Write Dxf binary files
  • Read/Write Dxf ASCII files
  • Read Dwg files
  • Write Dwg files
  • Extract/Modify the geometric information from the different entities in the model
  • Control over the table elements like Blocks, Layers and Styles, allows you to read, create or modify the different tables
Compatible Dwg/Dxf versions:
DxfReader DxfWriter DwgReader DwgWriter

Current development

Dwg Writer
  • AC1014
    • Produces a valid file but some entities are missing in the model.
  • AC1015
    • This version depens on the implementation of VP_ENT_HDR to work properly with the different Viewports
    • This is a particular and isolated DWG version, it uses a different compression system and file distribution, due this difficulties, this version will not be implemented any time soon.
  • AC1024 - STABLE
  • AC1032 - STABLE

Code Example

public static void Main()
	string path = "sample.dwg";
	CadDocument doc = DwgReader.Read(path, onNotification);

// Process a notification form the reader
private static void onNotification(object sender, NotificationEventArgs e)
