Once you have
Q3Radiant open use ctrl + tab to get to where you
are in the XY Top view. Lets set our grid snap to 8
for right now. Now create a brush that is 32 units
wide by 168 units long, and 8 units high. and place
it 2 grid units away from 0,0 (see Image1). I will
go into why we center this like that here in a few
minutes.

Ok, now that we have
our brush out, you will want to texture it how you
want the steps to look in the final staircase (to
save you hours of doing it later). Now clone the
brush and hit the Z-Axis Rotate button once. Now
move the new brush to where it is touching the
corner of the previous brush. Now do this two more
times until you have something that looks like Image
2.

Ok now that we have
that done, select all of the brushes (shift + left
click). Set your grid snap to 1 and hit the R key.
Now we are set up for cloning and rotating. Now hit
your spacebar once to create a clone of the 4
brushes, next we rotate the brushes to where it
looks like Image3.

Alright, now you se
how we are going to do this. Now just clone and move
each one (don't take it off of rotate it makes this
so much easier) until you have a flat disk.

Now we are almost
done. At this point we have a mess of brushes that
would most certainly look horrible if we loaded up
q3 right now. Now comes the tedious part. Select all
of the brushes and then hit ctrl + tab to get to
your XZSide view. Now set your grid snap back to
eight (or the height of your steps). Now deselect
one step. This is your starting step, now move the
selected brushes up one grid unit, deselect the next
brush, move it up one grid unit and so on. You will
begin to notice the stairs taking shape. The final
output should look something like this.

Ok that's it. If you
need to resize it in anyway just use the
selection.....scale command. I hope this was
informative and not to confusing.
