Hello,
i 've worked one both Microstation and Autocad for years.
DGN files ARE NOT raster based files, they are vector based !
but the Microstation GDI use a kind of raster system, that make design
not so beautiful than in Autocad, but make it work faster, even with
very large files.
With ustation, you never need to regen, and you switch from paperspace
to modelspace instantly.
before V8, Ustation was very fast because it was single precision based.
the problem was that you worspace was proportionnal to the precision you
needed.
it was a very big problem for me.
Now Ustation is double precision based, like autocad. Now it's a little
slower than V7, but it is still very much faster than Autocad.
Ustation load in a couple of second, my Autocad 2006 takes half a minuts ...
When you are friendly with Ustation, i think it is a good CAD program.
It as many many features that Autocad doesn't have, like NURBS, or
movies functionality.
But it also have some lacks regarding Autocad.
I think that for a newbie, Ustation can be a very good choice, because
it can work with many kind of files (DWG DXF DGN IGES etc ...)
But for an old Autocad drawer, it can be difficult to adapt, but it's
possible, Ustation now look like Autocad in many aspects.
For the G.I.S, i think Ustation is better than Autocad.
It also generate small HPGL/2 files, and have high level plotting
option, and possibility of plotting interactivity with VBA program !
