John,
A bird's eye view (BEV) is a small window that contains your entire
drawing. You can either pop it up when you need it or leave it on the
screen at all times. With a BEV, you can quickly pan and zoom around the
drawing. Say for instance that you are zoomed in and start a line command.
The line's end point is clear acroos the drawing, outside of the current
view. With a BEV, you can quickly zoom over to a view which contains your
desired endpoint and finish the line. You'd be amazed how much faster it is
than using zoom dynamic or restoring a top view and then zooming back in
again.
Pop up text menus is something that our DLDs use. They look and behave just
like a Acad pull down menu, expect they pop up at your cursor location. You
can fully customize them with your commands. Pop up icons are similiar,
except they pop up a table of graphic icons instead.
The "over $1000" boards don't offer any more real horsepower than
coprocessed boards. By this I mean that their vector drawing speeds are in
the same ballpark. They do, however, often include some nice software that
takes advantage of the board's capabilities. Rasterex is a good example of
this.
Generic CADD doesn't support display lists so it can't take advantage of
some of the fast drivers available for Acad. I'm not sure about Design CAD.
