With the improvements being made in the operation of the i-Model file format how can the version of each be ascertained.
You can find the *.imodel file version by simply following these steps.
*** Note ***
All MicroStation V8i versions are packaged with ItgDgnDbImporter 1.5.7.x but if both MicroStation V8i and CONNECT Edition are installed on the same PC then the higher version of ItgDgnDbImporter will replace the old one. This would then produce the corresponding higher version iModel, even using MicroStation V8i.
The latest releases of MicroStation CONNECT Edition (Update 6) and above produce iModel 1.6.
