Aleksander,
You can use the MXdraw sheet layout tools to assist you here and automate the viewport creation / scale of views. While in layout mode the view is managed as a preview so you can dynamically drag / adjust relative to the baseline geometry (which can be any cad graphic). Then with as acceptable layout the views can be publised as sheets in the active dgn or to a new dgn referencing back to the design model.
If you want to explore the pure DGN layout tools there are some good information on the AakInga wiki
