Attaching a Shapefile in Microstation Connect vs V8i

I have a shapefile attached to a .dgn that comes in aligned perfectly when opened in V8i, but when I open the same file in Microstation Connect or Descart Connect, it's shifted way off to the northeast.  I have tried detaching in Connect and reattaching, but it still comes in shifted.  When I open it again in V8i, it comes in correctly.  I have tried with and without a geographic coordinate system defined in the DGN.

  • I looked at your file its in us survey feet  but no CGS coordinate system applied to it .. mstn  cannot align other refs even shp files if your base file has no datum and coord system..., the shape files  have  prj files and you can read this with note pad and it tell gis and cad what the datum and projection is and  units for the shp files... then microstation will reproject  these to match the existing datum projection  which yours does not have... I looked inside the prj files they both have the  CGS NAD 83 HARN

    so you can add a CGS to your active file even though your using survey feet and I can only see us  feet in the prj in msnt assign a datum try CGS NAD 83 HARN  this should then align all the files.. also your using display set  I wouldnt  when trying to test things as display sets force levels off etc....

  • Hi Lorys,

    whether GCS is assigned to master or not is not important in this discussion (despite of it's recommended), because it's about why the same file is displayed correctly in V8i and not in CONNECT Edition.

    When there is not GCS used, references are attached 1:1, so there is no shift. When the same file is opened in another version, the result has to be the same and references cannot be shifted.

    Moreover, when all all files uses the same GCS, it's not important whether GCS is used or not, so it likely not help in the discussion.

  • the shape file has a projection defined, how can mstn  attach said file correctly without a cgs defined ?

    And if one used the same projection for both dgn and shp this would help to remove some variables as the cause of it  not working.

    More over others have reported that it indeed shifts in CE using the files as supplied, again applying the same cgs that is used in the shp files should make it work correctly and no shift in either versions... so it would seem CE is misreading the prj file interpretation or the way msnt CE  is reading where the data in in the dgn...
