DWGdirectX

Overview

DWGdirectX is an ActiveX control containing a rich set of tools for working with DWG data. It is suitable for small utility applications, rendering systems, file conversion, and many other tasks. Built on top of the DWGdirect C++ development environment, DWGdirectX puts stable, powerful, and mature DWG technology into the hands of ActiveX developers. 

Key Features

  • Supported DWG/DXF/BDXF versions:
    • Read support for 2.5 through 2010
    • Write support for 12 through 2010.
  • Render DWG/DXF files using any ODA rendering device (GDI, OpenGL, DirectX).
  • Recover and repair damaged DWG files.
  • Recompute dimension geometry from dimension settings.
  • Safely edit and manipulate DWG data programatically, including:
    • Explode an entity into a set of simpler entities.
    • Apply a transformation to an entity.
    • Modify arbitrary properties of database objects.
    • Many more.
  • Export DWG/DXF data to SVG, PDF, DWF, BMP.
  • Import DWF files.
  • Full support for "round-trip" data.  For example, when saving a 2007 DWG file back to R14, 2007-specific properties are saved to the R14 file as xdata and then restored if the file is loaded back into a 2007-compatible application.
  • In-house ACIS support which includes rendering (wireframe and shaded), and access to the underlying boundary representation data stored within an ACIS entity.

Limitations

Due to restrictions of the COM environment, DWGdirectX does not allow users to create custom entity classes derived from standard DWGdirectX entity types. Users interested in utilizing DRX technology to extend the DWGdirect object set should use the C++ DWGdirect environment.

System Requirements

Supported Operating Systems: Windows 2000, Windows XP, Windows Vista

Supported Languages: VB, C#, C++, other COM-accessible languages
