Hi,I have a 2 dgn file that it's created in microstation v7.Now I want to reproject them in UTM zone 32 wgs84. If we use V8 it looks fine but when we save them as V7 they will not mount over each other to coincide the coordinates(Problem of global origine).so I used the FME to reproject them and here weh we add the ref file it mout in the real position but we have some problem regarding cell (final cell is very big then the first )also there many burst in all association.Our goal is to get a a Dgn in UTMzone 32 wgs84 with no problem regarding refs or Cells.

It's possible with a set of MicroStation V7 DGN files to create a local coordinate system and move the DGN global origin so that a small number of maps are located correctly. That won't work with a large number of maps that span a substantial area of the world's surface because of the limited coordinate span of the integer coordinate system used by V7 DGN files.

The MicroStation V8 DGN format was introduced in 2001: see the History of MicroStation. It removes many of the limitations of V7 DGN files. The V8 DGN fomat adds new capabilities. In particular, its floating-point coordinate system means that V8 DGN model coordinates have a far greater cartographical span than the integer coordinate system used in V7 DGN files. In addition, Bentley Systems introduced geographical positioning so that a V8 DGN can have global coordinates and can therefore be positioned accurately anywhere on the world's surface.
You can't retrofit MicroStation V8 DGN capabilities into a V7 DGN file format. You can't ask MicroStation V7 to perform tasks that it was not designed to fulfill.
MicroStation V7 was obsolete fifteen years ago. Why do you want or need to use that old file format? Why not simply move to MicroStation CONNECT and take immediate benefit from a more flexible file format and a more capable application?

The Modular GIS Environment (MGE) is ancient. Developed by Intergraph (now Hexagon GeoSpatial), it dates back to the days of steam-powered computers. It used the progenitor of MicroStation, the Interactive Graphics Design System (IGDS), which is essentially the DGN V7 file format.
Intergraph declared MGE obsolete twenty-five years ago; it was superseded by a complete new technology, Intergraph GeoMedia, which does not use the DGN file format.
Bentley Systems developed MicroStation GeoGraphics, which was backwards compatible with MGE but was itself superseded in about 2005 by Bentley Map.
MGE is not a Bentley Systems product. In fact, it predates the existence of Bentley Systems. Have you contacted Hexagon about your problems?
Unknown said:I'm asking if we can use MicroStation V8 with old MGE?
MGE is a GIS. MicroStation is not a GIS. No, you can't simply substitute MicroStation for MGE.
Unknown said:Our Mst V7 is related with a MGE and Informix database and all our data was in V7
Informix is now owned by IBM and is at version 12. You probably need to consider bringing your database up to date.
MicroStation V8 can read/write/edit V7 DGN files. However, the current GIS product is Bentley Map, which uses MicroStation as its graphics engine. Bentley Map, therefore, can read your V7 DGN files and use them with its GIS database. Bentley Map can work with a database, but you would be better advised to post to the Geospatial Desktop Forum if you want details of that product concerning Informix.
