Userdefined coordinatesystem i PowerMap V8i

Since all the coordinate system and map projections were mmove to the baseline Microstaiton in v8i, this functionality has moved from the typical Map fucntionality to the underlying Microstation fucntionality. For instance, from the PowerMap v8i documentation.

• Geographic Coordinate System Support
  Apply geographic coordinate system from a coordinate system library
  Apply geographic coordinate system from a source DGN file
  Apply geographic coordinate system from an attached reference file
  Apply master geographic coordinate system to attached reference files
  Attach reference file using geographic coordinate system transform
  Attach reference file using AEC coordinate system transform
  Set geographic coordinate system as ACS
  Construct geographic coordinate system from Google Earth placemarks
  Support for multiple geographic coordinate system libraries
  Edit Reprojection Settings
  

This is now typically placed in the Tools->Geographic menubar for v8i.

Information related to the process of defining custom coordinate systems can be found in the Bentley PowerMap V8i (and Bentley Map V8i) user documentation in the "Upgrading a Custom Coordinate System from a Previous Version of Bentley Map or MicroStation GeoGraphics" section. This information is also available online at the following location:

New to Bentley products here, so require detailed steps...

Have a batch of as-builts that need to be reprojected to a new Coordinate System, my queries are:

 1- I have all transformation parameters of the new Corrdinate System. How do I incorporate them into the custom coordinate system in Microstation GeoGraphics?  (shift, rotation & scale.)

Nahrwan datum (using Clarke1880 ellipsoid) to WGS84 datum (realized by ITRF2000 coordinate frame) .

2- Do all cells, blocks and annotations get projected once done?

 Thank you,

Zak

All data is transformed however there are options to control how certain elements are transformed.  Check the MicroStation documentation under: Reprojection Settings dialog

Hello Jeff

Is there any good news when the geographic datum editor will come back!

We need it urgently if we shall go to the v8i editions of Microstation , Microstation Map and Powermap.
