Teigha®

Allows ODA members to build engineering solutions with these features:

  • Supported DWG™, DXF, and BDXF file formats:
    • Read support for files of version 2.5 through 2014.
    • Write support for files of version 12 through 2014.
  • Supported DGN file formats:
    • Read support for V7 and V8 DGN (including V8 XM and V8I).
    • Write support for V8 DGN.
    • Convert from V7 to V8.
  • Render drawing files using GDI, OpenGL, or DirectX with the ability to select entities.
  • Recover and repair damaged .dwg files.
  • Edit and manipulate CAD data programmatically, including:
    • Explode an entity into a set of simpler entities.
    • Apply a transformation to an entity.
    • Modify arbitrary properties of database objects.
    • Clone a database object.
    • Many more.
  • Export to SVG, PDF, DWF, BMP, STL, DAE (Collda).
  • Import DWF/DAE/DGN files into a .dwg database.
  • Support custom objects — members can create custom objects that are usable within any Teigha host application (compatible with .dwg files only).
  • Support external files such as font files (TTF/SHX), linetype files (LIN/RSC), and hatch pattern files (PAT).
  • Recompute dimension geometry from dimension settings.
  • Support transactions and undo/redo capabilities for .dwg file data.
  • Support partial .dwg file load capabilities, allowing fast access to small subsets of drawing entities (entities are loaded from disk only if they are explicitly accessed by the client).
  • Customize memory management allowing member applications to control memory allocation/deallocation.
  • Support .dwg file “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.
  • Support ACIS/Parasolid data internally, including rendering (wireframe and shaded) for embedded 3D solids and access to the underlying boundary representation data.
  • Implement custom commands.  
  • Sample source code applications
  • Integrate with third-party components. More details at Third Party Components.

 

Example Applications

Teigha comes with an extensive set of example applications that cover a wide range of user applications, including:

  • Specific to .dwg/.dxf files:
    • OdReadEx – Read a .dwg or .dxf file and extract entity level data from the file.
    • OdWriteEx – Programmatic creation of a .dwg file containing examples of most supported entity and object types.
    • OdCopyEx – Load any .dwg or .dxf file and save as a specified version and type.
    • OdDwfImportEx – DWF import capabilities.
    • OdDwfExportEx – DWF export capabilities.
    • OdaMfcApp – MFC application which demonstrates rendering, entity selection, grip points, PDF export, custom commands, and many other features.
    • Many more.
  • Specific to DGN:
    • ExDgnDump - Read a DGN file and extract entity level data.
    • ExDgnCreate - Programmatic creation of a V8 DGN file containing examples of most supported entity types.
    • OdaDgnApp - MFC application which demonstrates rendering, PDF export and many other features.
