Description	The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.	DGN is the name used for CAD file formats supported by Bentley Systems, MicroStation CAD programs. The DGN format is used in construction projects, including buildings, highways, bridges, process plants, shipbuilding. DGN is a competing format to Autodesk's DWG.
Technical details	The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.

I (Frank Warmerdam) have implemented a Microstation DGN reading library on contract to Avenza Systems Inc., makers of MAPublisher. The library will be OpenSource (under my usual X/MIT license), portable and callable from C/C++. While it has been incorporated into my OGR Simple Features library, it is also be usable standalone with minimal overhead. The dgnlib library, and thispage of DGN related information are primarily hosted at http://dgnlib.maptools.org.

Dgn Microstation Viewer Freeware DWG Viewer v.3.06 View AutoCAD drawings with this free DWG/DXF/DWF viewer. The program is a small application wrapped around an ActiveX component. Batch converting DGN files to Image. AIGraph CAD Viewer, support DGN file format file open and view. Batch conversion dialog can help you convert DGN files to Image. Steps: Open AIGraph CAD Viewer first. Click 'Batch conversion command' button on the toolbar, or from 'File' menu. In Batch conversion dialog, add DGN files you want to convert.

DGNLib is a small C/C++ library for reading and writing DGN files.

Where can I get the source code?
dgnlib-1.11.zip: Current standalone sourcewith dgndump example mainline.
Does DGNLib support all DGN elements?
No, but it does support most 2D and 3D elements. Some of the more esotericelements are read in 'raw data mode', but not interpreted. It does support lines, line strings, curves, bsplines, ellipses, arcs, and text elements, as well as extracting color tables, and mastercoordinate information.
Does DGNLib support Microstation V8 DGN Files?
No, they are a substantially different format, and are not recognised atall. The DGNdirect library from the OpenDWGAlliance does support DGN v8.
Is it portable?
Yes, fairly, though as distributed it may be necessary to tweak the cpl_port.h and cpl_config.h files for different platforms. It was developedon Linux for a client deploying on MacOS, and Windows.
Does it require alot of memory?
Generally speaking no. Only one element at a time is kept in memory. Ifthe file is 'indexed' an additional 12 bytes per element is kept in memoryafter a pre-scan, but this isn't required.
Does DGNLib include code to draw DGN elements?
No, but there is a document that tries toindicate how to properly draw DGN elements given the structures returned byDGNLib. The OGR layer re-interprets the drawing information into OGR Feature Styleformat which is understood by some applications such as UMN MapServer. Cms 3.0 download.
What is the license?
DGNLib is under my usual MIT/X style open source license. Thus is can beeasily used in commercial, and free products with no concern about licensingissues. See the header of any source file for the full license text.
Is there support for writing DGN files?
Yes, there is preliminary support for writing 2D and 3D DGN files in recent releases.

Is there documentation?
There is a detailed DGN Library API Reference available. There is currently no tutorial style information on how touse the library, but the dgndump.c utility can serve as a limited example.
Is further work going on to improve the library?
The initial project is complete, but I am interested in fixingbugs and adding minor features. Improvements are welcome.
