CADEditorX is an ActiveX component for adding CAD features to the Web page or to the application under development in any development environment supporting ActiveX and COM technology, for example C#, Visual C++, Delphi, VB, JavaScript etc. It enables viewing, editing, converting, printing and measuring DWG, DXF, SVG, HPGL, STEP, IGES, STL and other CAD files. An easy-to-use API and numerous examples allow fast integration of CADEditorX to the final application.

CADEditorX scope of use:

  • database systems;
  • monitoring and remote control programs;
  • CNC machines;
  • CAD applications development;
  • data export to CAD formats;
  • document management systems and highly specialized products.
