MicroStation V8i makes it simple to plot the contents of a cell library. Just open the cell library as the active file and choose Place Cell Index from the Cells task. Tweak the settings and enter a data point on the view. MicroStation will build a convenient print-ready grid. Since this grid is composed of references to the cell models, it will always be current!
To plot the contents of a V7 cell library, try CellUtil that came from Snutter.
