CadLib 4.0 Features

  • Import and export DWG files (versions versions 13, 14, 2000, 2004, 2007, 2010, 2013 (AutoCAD™ 2013-2016))
  • Import and export DXF files (versions versions 12, 13, 14, 2000, 2004, 2007, 2010, 2013 (AutoCAD™ 2013-2016))
  • GDI+ 2D and 3D wireframe rendering.
  • WPF wireframe rendering.
  • OpenGL surface rendering.
  • Great type safety: there are a number of DXF entities which have sub types. Like no other competitor CadLib has separate classes for these sub types. The DxfDimension class for example has sub classes for linear, aligned, angular, radial, diametric and ordinate dimensions. The benefit for the developer is that creating DXF is made easy and creating valid DXF files is by design almost automatic.
  • Pick engine for mouse selection.
  • Utility class for export to .bmp/.jpeg/.png/.tiff/.gif
  • Export to PDF, PostScript, SVG, XAML
  • Copy (clone) entities, even across DXF files
  • Supports entity extended data.
  • Both ascii and binary DXF supported
  • Unpacks compressed DXF files (zip, tar, bz2, gz)
  • 100% .NET code. All DXF objects exposed as .NET classes. Convenient enums are provided for all flags in DXF.
