As Lars wrote, first get an idea of the geometry you want
to see and find the coordinates for the view point and a
view directions. Once you have started rvu press 'v' and
fill in the view parameters (view point, direction, up,
angle, clipping). Repeat with small changes until you have
a nice view.

You can save the final view parameters but also the image
('W') to a file. The clipping is useful to create parallel
and perspective views that are physically impossible (eg.
a perspective of the interior of the room from the outside).

Read the man page for rvu. It tells you all the tricks.
