A project has seed file of 2D of default design model, default sheet model & DPF sheet model. How to convert all these 2D seed to 3D in MX Road SS4 V8i?

Question

Vaibhav, a 2D seed/file has 2 dimensions, that means it considers only the X,Y. Where as any terrain data like Google Earth or point clouds has 3D data, that it X,Y,Z or Lat, long, elevation. So in order to import such data you need a 3D file / model. You can try to create a new model within this file, and select 3D and work in this model to import the terrain data. Hope this helps.

The 'Project' changes the configuration so that it looks at particular folders for things such as seed files, level libraries, cells, feature definition libraries etc. The 'Untitles' project does not have anything defined - whereas the 'Metric' project has everything set up for a metric project. 
 A quick way to see the difference is to open a file with 'Untitled' as the project, and check what levels are available in Level Manager. Open the same file with 'Bentley-Metric' and do the same - you will see a big difference. Note - the DGN itself has not changed, but the libraries that you are pointing to have. 
 NOTE: as this is a completely different topic to the original 'seed file' subject, you should really create a new thread for it.

Frank - you do not seem to understand the idea of Feature Definitions [FD]. They are in the DGNLIB - a library, not a seed file. Why are you trying to make a FD 3D DGNLIB - it makes no sense. 
 When you create a new file File > New, you can pick a 2D seed file or a 3D seed file in the dialog, and your file is 2D or 3D. The seed files are in a 'seed' folder - check your folder structure. 
 The FD will be read from the DGNLIB as needed - they have nothing to do with 2D/3D..
