Hello Vaibhav, 
 As you are using MXRoad, you will have to set 3 seed files as shown in the attached snapshot from File Management toolbox. 
 Path of my system : C:\ProgramData\Bentley\MX V8i (SELECTseries 4)\WorkSpace\System\seed

To get MX Configuration window, you will have to set MX menu, View > Configuration > File Management.

If you are using the OpenRoads tools, use the CAD menu (File > New) to create a 2D file - select a 2D seed file, not one of the MX seed files. Ensure that the working units are metres - just to be sure. (You would only pick a 3D seed file if you were creating a terrain.)
